The `Baby` hitmaker - who shocked fans when he changed his signature hairstyle recently - gave chat show host Ellen DeGeneres a lock of his hair when he appeared on her show and she promptly put it up for auction on eBay receiving bids of $10,000 within one hour. The auction closed on 02.03.11 with the successful bidder paying a whopping $40,668 for the tresses plus a chance to meet the teen sensation next time he appears on Ellen`s chatshow. Ellen has donated the fee to charity The Gentle Barn Foundation, Meanwhile it has been revealed that Justin celebrated his 17th birthday on 01.03.11 in a $6,000-a-night suite at the St. Regis Monarch Beach hotel in Dana Point, California with girlfriend Selena Gomez. A source said: "For the most part, Justin and Selena wanted to be left alone. They didn`t have bodyguards or parents with them, but there was an emergency contact list at the front desk with numbers for a bodyguard and some of their people`s info if they needed it in any way." The Presidential Suite where they stayed comes with a butler on call, two bedrooms, a dining room to seat 10, a private balcony overlooking the ocean and a hot tub. Despite their lavish surroundings, the couple - who went public with their romance at the Oscars on Sunday night (27.02.11) - were seen enjoying a romantic dinner at the nearby Stonehill Tavern.
