Justin Timberlake bought drinks for an entire Las Vegas nightclub. The generous star made an unscheduled appearance at Palazzo's Lavo nightspot on Tuesday, and treated partygoers to a free shot of his tequila, called 901.

He told guests: "This is a very special evening. Me and my buddy started a home grown tequila down in Mexico and I wanted to make sure you guys got a taste, so I bought everyone in the bar a shot."

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.

Guy Ritchie's pub is being monitored after receiving noise complaints. The Punch Bowl, located in London's exclusive Mayfair district, has been branded too raucous by furious residents living near the drinking establishment.

Westminster council has decided to install equipment to monitor the sound levels and Guy could even lose his license to serve alcohol if it is found to be too noisy.

Britney was the recipient of the "Ultimate Choice" Award at the 2009 Teen Choice Awards at the Gibson Amphitheatre on Sunday. The award is given to celebrate career-spanning achievements.

The ultimate surfboard was preceded by a career montage of Spears, who first hit the "Teen Choice Awards" stage in 1999. "Wow, this is such an honor. Thank you guys so much," Britney said upon receiving her surfboard. "I'm so happy to be here tonight with all of you. From the bottom of my heart, thank you so much and God bless."

Ciara says it is Justin Timberlake's responsibility to make sure Michael Jackson's memory lives on.

The "Love Sex Magic" singer insists it is down to stars of her generation - including the "SexyBack" hitmaker, who has copied many of Jackson's trademark dance moves - to embrace the musical legacy of the pop icon, who died of a suspected cardiac arrest last month.
