(Cover) - EN Showbiz - Kate Hudson and former flame Owen Wilson caught up on old times as well as new additions to their families on Sunday.

Kate and Owen dated between 2006 and 2007 after working on You, Me and Dupree together but had an intense break up.

Us Weekly reports that the pair had a chance reunion at the Vanity Fair Oscar Party which was held at the Sunset Tower in West Hollywood.

"[They] totally had a moment," a fellow reveller told the publication. "They hugged and kissed on both cheeks."

Kate and Owen both welcomed children into the world last year and couldn't wait to show each other pictures of their offspring.

Kate gave birth to son Bingham in July while Owen and girlfriend Jade Duell were delighted with the birth of their son Robert Ford in January 2011.

"They pulled out their phones to show each other pictures," the eyewitness said. "They both oohed and ahhed over them."

Kate was apparently in a great mood at the bash and was even seen talking and laughing with Cameron Diaz who she had reportedly been feuding with.

Cameron and Kate's friendship apparently went through a rocky patch when the Bad Teacher star started dating Kate's ex-boyfriend Alex Rodriguez.

But all seemed to be water under the bridge and they were happy to be photographed together while they drank champagne.

Kate is now engaged to British rocker Matt Bellamy. (C) Cover Media
