Karina Smirnoff and Mario Lopez won't be dancing off into the sunset and Nicky Hilton wants to dance as far from Kevin Connolly as possible!

Pop Tarts has confirmed that after almost two years together, "Dancing With the Stars" sweethearts Karina Smirnoff and Mario Lopez have ended their romantic relationship.

Despite reports earlier this year that the couple had split, a rep for Smirnoff told Tarts that this is the first time they have broken up. But while both Smirnoff and Lopez released statements last week wishing each other well, an inside source said that the breakup was far from clean.

The twosome reportedly ended it all over the phone on Wednesday evening in New York City, where Mario is guest starring in "A Chorus Line" on Broadway while Smirnoff was in town for numerous public appearances.

"I don't think they'll be best friends anytime soon," the source said. "The circumstances are too upsetting for Karina to discuss, but she knows she'll be better off having time to focus on her career."

Speaking of which, Smirnoff isn't taking time off to wallow in any tears. The in-demand dancer is off to Sin City this weekend for a string of appearances, followed by a whirlwind schedule that will take her straight to Connecticut and San Antonio, Texas.

She'll also be promoting her upcoming dancing workout DVD set and possible book, and doing a cameo appearance on "Project Runway." Phew.

Paris Performs While Nicky Locks Lips

After a hard day’s work in Las Vegas shooting scenes for her upcoming MTV reality series “My New BFF," Paris Hilton hit up hotspot The Bank on Saturday night to celebrate nightlife impresario Danny A’s birthday.

The hotel heiress hung with her beau Benji Madden and boogied on the banquettes while sis, Nicky, spent most of her time making out with her boyfriend Dave Katzenberg.

However, the younger Hilton was reportedly a little red-faced about her ex Kevin Connolly also being at the bash. Eyes on the scene told Pop Tarts that it was all very awkward and that Nicky never approached her former flame and totally avoided the end of the VIP balcony where he was chillin’ with fellow actor Lukas Haas.

Danity Kane: Diddy's Divas Squabble in Sin City?

It seems as though the girl group Danity Kane (produced by Sean "Diddy" Combs) is falling apart — again. Rumors of a breakup started circling earlier this year, and although they’re officially still together, we’re starting to question how long it will last.

According to an insider, two members of the five-gal band got into fisticuffs backstage before their Sin City concert at The Pearl on Friday night and delayed the show by 20 minutes.

But apparently the bitching blew up even more at the after-party held at hotspot Prive. Arriving at 1 a.m. (an hour past their scheduled appearance time), we’re told the singing sensations fake-smiled for the cameras yet were anything but friendly to each other once inside. Three members sat at one VIP booth while the other two positioned themselves away throughout the party, adding to the already mounting tension.

Danity Kane member Aubrey O’Day, however, refused to let the squabbling spoil her night in Sin City as she reportedly got friendly with numerous different guys well into the wee hours. …

Reps for the group did not respond to requests for comment.

Schwarzenegger Picks Marilyn

David Beckham did it, now California Gov. Arnold Schwarzenegger has done it too.

Last year, Becks purchased a near-naked portrait of Marilyn Monroe from the swanky Beverly Hills-based gallery The Celebrity Vault to hang in the master bedroom of his Hollywood home as a gift to his wife, Victoria Beckham. But it seems "Terminator"-turned-politician Schwarzenegger also has an expensive soft spot for the screen siren.

Pop Tarts confirmed that Schwarzenegger just purchased an original portrait of Monroe (covered only by a bedsheet) from the same place to complement the James Dean he also bought recently.

“Initially he was interested in some of the male music figures,” our source said. “But then he fell in love with the very candid Marilyn shot.”

The sassy snap is rumored to be worth several thousand dollars.
