Shanna Moakler has reunited with her rocker husband Travis Barker, she tells PEOPLE exclusively, but denies rumors she's pregnant.
"While I hope one day to have more children with Travis, I am not pregnant," says the former Dancing with the Stars
contestant. "But yes, I'm madly in love with my husband."
Barker, 31, the drummer for Blink 182, threw an early 32nd birthday for Moakler over the weekend at Miami's Cameo nightclub.
"They were really affectionate with each other all night long," says a partygoer. "They really looked loving and happy."
More than 100 guests, including Kimberly Stewart and Mark McGrath, watched Moakler – whose real birthday is March 28 – blow out the candles on her cake while Barker sang an off-key rendition of "Happy Birthday." Moakler then kissed Barker on the lips while the crowd applauded.
The two also were spotted over the weekend strolling hand-in-hand and kissing on a Miami beach.
The couple, who appeared in their own MTV reality show Meet the Barkers
, have two children together. They endured well-publicized ups and downs even before Barker filed for divorce
Barker's reps declined to comment.
