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."

Cameron Diaz is reportedly dating Jason Lewis. The "My Sister's Keeper" actress attracted attention with her flirty and affectionate behavior towards the "Sex and the City" actor during a recent meal together at a sushi restaurant in Venice Beach.

An onlooker said: "Cameron and Justin were sitting in the corner of Shima totally wrapped up in one another. They couldn't stop touching each other. And we couldn't stop looking."

Renee Zellweger grabbed Bradley Cooper's butt during a trip to Barcelona. The "Case 39" co-stars - who are rumored to be dating - flew to the Spanish city on Saturday and onlookers claim they couldn't keep their hands off each other as they enjoyed several romantic dinners.

One said: "Bradley and Renee seem smitten with each other and at one point she cheekily grabbed his behind."

Gerard Butler wants to date a "dumb woman." The "Ugly Truth" actor, who has been romantically linked to Jennifer Aniston, is attracted to different types of women and has no idea what he really wants from a relationship.

He said: "I couldn't actually tell you what I look for because it's different in each woman, but part of it is being smart and part of it is being dumb."
