Jennifer Aniston thinks "laziness" makes relationship fail. The 40-year-old star - who is divorced from Brad Pitt and has endured splits from actor Vince Vaughn, model Paul Sculfor and singer John Mayer - insists romances only work if both people strive to make each other happy.

She said: "Why does the romance leave relationships? I think it's laziness. I really do. I think a good relationship is about collaboration. That's the way to go in a relationship."

Rihanna saved $3 million on her new mansion. The "Rehab" singer reportedly negotiated the enormous discount on the luxurious eight-bedroom home in Beverly Hills after convincing real estate agents to drop their price.

The hillside house features 10,000 sq ft of floor space, 10 bathrooms, a recording studio, pool, gym, spa, library and a home cinema and was initially listed at $9.95 million.

Jennifer Aniston still wears the gold Rolex watch given to her by an ex-boyfriend. The Hollywood beauty has been spotted sporting the luxury timepiece amid rumors she and singer John Mayer have rekindled their romance and are meeting up for secret romantic trysts.

A source said: "John gave Jennifer the Rolex when they were at the height of their romance in May 2008. Jennifer hardly took the watch off, but when they split she stopped wearing it. In recent weeks she's started wearing it again to show John he's still in her thoughts."

Jennifer Aniston will only date celebrities. The 40-year-old actress - who is divorced from actor Brad Pitt and split from musician John Mayer earlier this year - prefers to have relationships with people who are already in the spotlight as she knows they will empathize with her hectic lifestyle.

A source told Us Weekly magazine: "Jennifer won't date a normal guy. She goes after the hottest thing of the moment."

Jessica Biel is the most "dangerous celebrity" on the internet. According to security technology company McAfee Inc, online searches for the 27-year-old actress - who is dating Justin Timberlake - are more likely to spread computer viruses than any other star.

The company - who last year found Brad Pitt to be the most "dangerous" online celebrity - said there was a one-in-five chance that looking for information, wallpapers, images and videos of the "Easy Virtue" star would lead users to a website designed to cause damage.

Jennifer Aniston and Gerard Butler have been stealing kisses with each other on the set of their latest movie. The pair - who refuse to confirm rumors they are dating - are said to be smitten and are all "lovey-dovey" in between filming scenes for "The Bounty."

An on set source said: "We saw him give her a little kiss. They were very lovey-dovey."
