Katy Perry and Josh Groban are dating. The "I Kissed A Girl" singer has been on a series of intimate dates with the singer-songwriter, but the pair are keen to keep their fledgling romance out of the spotlight.

Paris Hilton's boyfriend is set to propose. Doug Reinhardt - who has been dating the hotel heiress since last month - is keen to tie the knot and has asked her father Rick for Paris' hand in marriage.

A source said: "Doug is smitten with Paris and wants to spend the rest of his life with her. He's already found the perfect ring, asked her father for permission and is now waiting for the right time to pop the question."

Paris Hilton has been told to stay single by her mother. The blonde beauty has been given some words of wisdom by Kathy Hilton, who believes her daughter feels under pressure to constantly have a boyfriend.

She said: "My dating advice for Paris would be just to take your time. It is OK to be alone. You don't have to always be with someone."

The Hard Rock Hotel and Casino in Las Vegas has confirmed that Paris Hilton will be celebrating her 28th birthday in its nightclub, Body English, the weekend of March 6th. Hilton held her 25th birthday party in Las Vegas two years ago at Pure nightclub in Caesar's Palace.

Even though her birthday has passed (it was February 17th), PR reps for the Hard Rock say that Hilton's official bash is Saturday night in Body English, with two private parties in the penthouse suite with 30 of her closest friends.
