If there were any doubt about the relationship status of Kate Hudson and Lance Armstrong, who sparked romance rumors recently by spending the weekend together in Texas, that speculation was put to rest Friday night in the restroom of a party in Cannes, France.

At the annual party thrown by fashion giant Dolce & Gabbana, Kate and her cyclist beau were openly getting romantic, sharing kisses and embraces in the crowded VIP area of the bash inside Baoli restaurant. "Rather than draw attention to themselves by demanding a table, they jostled for space on the dance floor," one witness tells OK!. "They swayed with each other and kissed and laughed and held hands."

But sealing the deal on this couple’s status was a very domestic moment inside the party’s bathroom, where a partygoer caught the actress bent over a sink, where she was cleaning a white men’s shirt. "I asked her what she was doing," recalls the source. "Kate blushed and laughed — And then Lance walked out of a stall topless!"

If that’s isn’t domestic bliss, what is?
