This Rihanna/Chris Brown thing just won't go away.

Just a week after the 23-year-old singer appeared to cozy up with Nicole Scherzinger, Brown and his Rihanna apparently played tonsil hockey while partying at New York City hotspot Griffin.

Brown, joined by pal Bow Wow, arrived at the club first and settled into his own table, according to E! News. Rihanna arrived later, and sat at a separate table from her ex.

"She knew he was there," a source said.

That's the kind of information you just won't get just anywhere.

At one point during the night, Brown climbed over his table to join Rihanna. She then proceeded to take off his shirt before they began dancing and making out, according to an eyewitness at the club.

Wow. Imagine what would happen if these two ran into each other somewhere private?

Following their dance session, Brown left the club just before 4 a.m., with Rihanna hitting the road about five minutes later.

That's probably just a coincidence.

Reps for Brown, 23, and Rihanna, 24, did not immediately comment.

Brown is still on probation for beating Rihanna up in 2009. Which doesn't seem to bother her anymore. They have remained close, however, exchanging birthday tweets in recent months and even sharing a friendly peck during last month's MTV Video Music Awards.

KHLOE AND MARIO LIKELY TO CO-HOST 'X FACTOR': Khloe Kardashian and Mario Lopez will be the new co-hosts of "X Factor," according to TMZ.

The website reported Tuesday that the finishing touches are being put on their contracts, but the announcement will be made some time this week.

Having co-hosts will add millions to an already-enormous show budget, with Judge Britney Spears leading the way with a cool $15 million per season. TMZ reported a few weeks back that Kardashian may have a scheduling conflict with her family's reality show, but apparently that's been cleared up.

Thank heavens. I think we can all agree that there's just not enough programming featuring people named Kardashian.

If everything works out, Kardashian and Lopez would debut on "X Factor" in November.

'GREY'S ANATOMY' STAR SUING BILLY CORGAN: "Grey's Anatomy" star Eric Dane is suing his neighbor, Smashing Pumpkins frontman Billy Corgan, claiming a falling tree nearly killed Dane's pregnant wife Rebecca Gayheart.

Dane filed the lawsuit this week in L.A. County Superior Court, alleging one of Corgan's trees crashed through his Beverly Hills home during a nasty storm last year, flooding the house and breaking a giant power line. Dane alleges Gayheart -- nine months pregnant at the time ---had to evacuate a "quickly flooding" home while dodging live high-voltage wires, according to TMZ, which posted pictures of the damage.

Dane says Corgan was warned about the dangerous eucalyptus trees on his property and failed to take action.

Guess Dane never heard Corgan's "The killer in you is the killer in me" line.

Corgan told TMZ the allegation is "patently untrue" and insisted he was never warned about his dangerous trees and didn't realize they posed a threat until it was too late.

He also apparently wasn't warned that firing his whole band would seriously put a dent in his career.

Corgan said, "I was horrified when I learned about the tree falling during what was a massive storm, a storm with winds strong enough to uproot a 50-foot tree by its base! Thankfully no one was injured."

Corgan said after the storm he had dangerous trees removed from his property. He also called the lawsuit "a shame, because (Dane and Gayheart) are nice people."

Then why does he keep trying to drop trees on their house?

The couple is suing for nuisance, negligence and injunctive relief, asking for unspecified damages.

MARIA SHRIVER NOT TALKING ABOUT BOOK: Maria's not talking.

Unlike ex-husband Arnold Schwarzenegger, who was happy to sit down with "60 Minutes" and talk about his tell-all memoir, "Total Recall: My Unbelievably True Life Story," Maria Shriver hasn't spoken publicly about the end of her marriage.

And she apparently isn't going to anytime soon, despite offers from everyone from her old friend Oprah Winfrey to her old network bosses at NBC, according to the Huffington Post.

"We'll have no comment," said Matthew DiGirolamo, communications director for Maria Shriver. That means no comment on Schwarzenegger's new memoir, in which he covers everything from his affair with the couple's former housekeeper that produced a now-teenage son, to his tryst with former "Red Sonia" co-star Brigitte Nielsen while he was dating Shriver.

"This must be a very painful time for her," a former NBC colleague of Shriver's told Huffington Post. "Maria is a very private person who doesn't enjoy seeing her personal life on television or in magazines. She has been offered every opportunity to tell her side of the story and it doesn't surprise any of us that really know her, that she has declined all of them."

Schwarzenegger, who told "60 Minutes" that Shriver had not read the book, continued to promote his book Monday on "CBS This Morning."
