Paris Hilton sparked rumours she is getting serious with The Hills' Doug Reinhardt after they spent Valentine's Day weekend together.
Doug - who split from 22-year-old Hairspray star Amanda Bynes last month - even gave Paris, 28, a gift, according to E! Online, of an Andy Warhol print of Marilyn Monroe.
Paris' grandmother called her Marilyn Monroe when she was a little girl and Paris once said in an interview "There's nobody in the world like me. I think every decade has an iconic blonde, like Marilyn Monroe or Princess Diana and, right now, I'm that icon."
Doug was also with Paris the night before Valentine's Day when she threw a pink-themed party to celebrate her 28th birthday early, her actual birthday is on February 17.
But a source said: "Paris is not serious right now with anyone."
The socialite broke up with Benji Madden last November after dating for nine months, but said she would always love him.
