Christina kisses Enrique

As if winning a Grammy wasn't enough, Christina Aguilera is now being linked to one of the most lusted-after pop stars in the world.

Christina and Enrique Iglesias were spotted dancing very closely after VH1's "Men Strike Back" concert, and the dancing soon turned to kissing, the New York Post reports.

"They just started going at it," an eyewitness told the paper. "They were kissing very deeply, very passionately. They weren't trying to hide it at all."

After the two pop stars were finished locking lips, the Latin singer left the club. Aguilera left about 10 minutes later.

"I know they were dancing, and it could have been very suggestive. I don't know if they were making out. But I do know they didn't go home together," Christina's publicist said.

"I know that Enrique and Christina have been friends since they performed together at the Super Bowl halftime show," Enrique's spokesman said. "But since I was not at Nell's, I can't confirm or deny what happened."

In more Christina news, the singer is responding to rapper Eminem's insults.

Eminem's upcoming single, "The Real Slim Shady," allegedly features lyrics that describe Christina performing a sex act.

"It's disgusting and offensive and above all it's not true," Christina told MTV.

The blond singer's manager explained why the song was so offensive.

"There is nothing more important to a woman than her honour, and that seems to be what we're dealing with here," he told The Post.

Eminem's management had no comment about the controversial song.
