Paris Hilton is considering marrying Doug Reinhardt.

The socialite - who turned 29 last Wednesday (17.02.10) - belatedly celebrated her birthday with 'The Hills' star in Las Vegas on Saturday (20.02.10) and admitted she couldn't be happier.

When asked if they were planning to wed, she said: "We'll see what happens in the future, but right now we are so happy to be together and we are really in love."

Paris and Doug were joined at nightspot Tao by her parents Rick and Kathy Hilton, who appear to have given their daughter's romance their full backing.

During the evening, Paris tweeted: "Vegas is crazy! I've never seen Tao so packed! It seemed like it was New Year's Eve! GREAT Night!

"What a fun night! My mom and Doug were so cute dancing together! I love how my parents love my love! We all had a blast! Great night! (sic)"

Doug also took to twitter to gush about the family occasion.

He posted: "What an amazing night with Mr. and Mrs. Hilton along with my beautiful princess."
