Paris Hilton and boyfriend Thomas Gross made quite a splash earlier this summer when we snapped them kissing on his yacht off the coast of Spain, and now they're taking things to the next level!

P posted the above shot on Instagram last night and wrote, "Soulmates," and she's already introduced him to her family! A source tells The Daily Mail, "They had dinner with her family in Los Angeles last week. Her mother Kathy really liked him and was telling everyone that she is happy her daughter has met such a great match." A family insider added, "Friends and family were asking since Nicky is getting married now, is Paris next? They would make the perfect couple."

After meeting in France earlier this spring at the Cannes Film Festival, the two enjoyed a romantic getaway to Cabo San Lucas, Mexico, where Paris' cousin Brooke Brinson got married. In June they traveled to Ibiza, where Gross owns a villa. Paris' main man is based out of Zurich, Switzerland and he's estimated to be worth about $200 million.

Sounds like hubby material to us! And that body? Click the gallery below to see more of the two lovebirds on their romantic vacay last month!
