The fireworks have fizzled for Katy Perry and John Mayer. The pop star, 27, and crooner, 34, who were linked this summer, are no longer dating, a source confirms. "They'll end up as friends," the source says. "They were honestly having fun. People made it out to be far more than it was." The pair – whose outings included dinner at Chateau Marmont and an animal-filled birthday bash at a Hollywood talent agent's home – seemed like a good match, according to a source who saw them together in August."They almost acted like they've been a couple for a long time," the observer said. "It definitely didn't seem like a new relationship." Perry was recently divorced from Russell Brand, and dated Florence + the Machine guitarist Robert Ackroyd earlier this year.

Robert Pattinson managed to (mostly) avoid talking about his personal life on Jimmy Kimmel Live! Wednesday – but he did make reference to his rootless living situation. "Last time you were here, I think you were homeless, right?" Kimmel asked the star, who has been on a publicity tour to promote his new movie Cosmopolis. Pattinson took a brief pause, nodded and answered, "Still am." In July, Pattinson left the home he shared with girlfriend Kristen Stewart after it was revealed she cheated on him with director Rupert Sanders. Pattinson then went to stay at Reese Witherspoon's home before reappearing to publicize his film. Asked if he was living in hotels, Pattinson joked, "No, I rented this archway and I just live behind it... in this big trash can."

After that, Pattinson made no more reference to his relationship and instead told Kimmel about how he'd spent several months taking up cycling until he realized he'd been biking near a place that was a popular pick up spot for men. "I used to turn up looking at everyone in the parking lot thinking, 'Why are all these guys sitting around in their cars all the time?' And I'm going there every day... in my little Lycra [bike] pants," Pattinson said. "And one day there was a big raid as I was there."

We mentioned the other day how the divorce between Katie Holmes and Tom Cruise was finalized in record time. Now, we’ve learned that Katie Holmes walked away with nothing other than rather modest child support in her divorce from Tom Cruise ... and we have the breakdown. Sources familiar with documents filed with the court say Katie got no lump sum payout, which is consistent with the prenup which essentially shuts her out of Tom's $250 million fortune.As for spousal support, Katie got nothing.

Katie will get money for child support, but it's way less than a judge could have ordered.  According to the settlement, Tom must pay Katie $400,000 a year in child support.  That comes to $33,333.33 a month.  The money will be paid by electronic transfer. Tom must pay Suri's support for the next 12 years, until she turns 18.  All tolled, that comes to $4.8 million. Tom must also pay Suri's expenses, including medical, dental, insurance, education, college and extracurricular costs. And, both Tom and Katie agree that Suri will not attend a "residential school" from now through her high school years. Translation… she can't be shipped off to boarding school - Scientology or otherwise.

Katie could have gotten more child support under New York law if the case went to trial, but both she and Tom decided to settle quickly. When news first broke about Katie leaving Tom, rumours swirled that she wanted nothing from Tom other than a divorce and it looks like that's exactly what she got.

So Taylor Swift is a wedding crasher! Who would have thought?! The country singer's rep has denied any truth to Victoria Gifford Kennedy's recent claims that she refused to leave a wedding she wasn't invited to, but Kathie Lee Gifford  set the record straight during The Today Show yesterday. Gifford was at the Kennedy wedding in question and can personally confirmed that Victoria "said very nicely, 'Please do not come.'"

It's hard to argue with the woman who was actually present while all the drama went down, but it sounds like Conor Kennedy deserves to bear more of the blame than Swift. Here’s the background… Conor had been asked to RSVP months before the event and he waited until "an hour before the wedding" to ask if it's cool to bring his famous girlfriend. Victoria then told Conor NOT to come, but he did anyway and brought the highest paid celebrity under the age of 30 with him! Can we say… awkward!!

Lance Armstrong has quit the race. The seven-time Tour de France victor announced Thursday he will no longer fight his investigation by the U.S. Anti-Doping Agency – meaning he will be banned for life from ever competing again, reports CNN. Late Thursday, the USADA confirmed it will also strip Armstrong of all results since Aug. 1, 1998, reports USA Today. "There comes a point in every man's life when he has to say, 'Enough is enough.' For me, that time is now," Armstrong, 40, said in a statement.

This latest turn of events began to unfold in June, when the quasi-government agency (recognized as the official anti-doping agency for Olympic, Pan American and Paralympic sports in the U.S.) accused Armstrong of using, possessing, trafficking and giving to others performance-enhancing drugs, as well as covering up doping violations. Armstrong, as he had in the past, vigorously denied the charges."I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one," he said on his website, where he also accused the USADA of wanting to "dredge up discredited allegations," which he called "baseless" and "motivated by spite."

Armstrong, who has never been convicted of any doping charges, had been accused of doping before by other disgraced U.S. riders, including Floyd Landis and Tyler Hamilton. In February, the U.S. Justice Department closed a criminal investigation after reviewing allegations against Armstrong, apparently for lack of evidence that he used performance-enhancing drugs. Following news reports of Armstrong's decision Thursday, USADA chief executive officer Travis T. Tygart issued the following statement: "It is a sad day for all of us who love sport and our athletic heroes. This is a heartbreaking example of how the win-at-all costs culture of sport, if left unchecked, will overtake fair, safe and honest competition, but for clean athletes, it is a reassuring reminder that there is hope for future generations to compete on a level playing field without the use of performance-enhancing drugs." Of losing his titles, Armstrong said: "I know who won those seven Tours. The toughest event in the world where the strongest man wins. Nobody can ever change that. Especially Travis Tygart."
