Here is a new preview promo pic of Britney Spears with Ellen DeGeneres from a taped segment that is scheduled to air on The Ellen DeGeneres Show next Tuesday December 16. As you may recall, we got to see a few preview pics of Britney and Ellen all dressed up in old skool garb as the ladies went Xmas caroling last weekend together … this new pic looks much more relaxed (and comfortable):

Love it, love it! I can’t wait to see this segment. Additionally, Entertainment Tonight is advertising a new segment of their own where their cameras visited Britney and her sons Sean Preston and Jayden James in their home:

Fortunately for us, we won’t have to wait long until we’re able to watch this ET segment. It is scheduled to air on the show tonight. After the jump, check out a short preview video for the ET piece …

Jake Gyllenhaal sat down with Entertainment Tonight to talk for the very first time about his new movie Prince of Persia: The Sands of Time … and he looked pretty damn good all the while, if I say so myself. Here are a few screencaps from his brief interview with ET:

Jake Gyllenhaal plays a 6th century prince who holds the fate of the world in his hands in the sweeping fantasy-adventure ‘Prince of Persia: The Sands of Time,’ and ET’s Thea Andrews got up close and personal with the newly minted action hero on the London set! So, how did Jake get that buff bod? “I over-prepared myself because I never knew how much they were going to ask me to do, so I just made sure I’d be hopefully able to do anything,” a playful Jake tells Thea. The former ‘Brokeback Mountain’ star trained for months before the arduous Moroccan desert shoot, and has been training daily to maintain his action-hero physique, gaining five pounds of muscle. “I guess I’ve gotten buff,” he shrugs. “There’s a lot acrobatics in the movie — a lot of running up walls, and jumping on things and Parkour, so it requires muscularity, but it requires a lot of aerobic ability too.” When filming finally wraps, Jake promises with a smile, “It’s going to turn into fat and I’m going to be happy.” ‘Pirates of the Caribbean’ blockbuster producer Jerry Bruckheimer is bringing ‘Prince of Persia’ to life, based on the hugely popular video game and scheduled to open in theaters on May 28, 2010. The story finds Jake as Dastan, a young Persian prince who must join forces with the beautiful and feisty princess Tamina (played by ‘Quantum of Solace’ Bond girl Gemma Arterton) to prevent a villainous nobleman (Ben Kingsley) from possessing the Sands of Time — a gift from the gods that can reverse time and allow its possessor to rule the world. “I’m running away from family and I’m running away from bad guys and I’m trying to prove my innocence,” says Jake, trying to keep the play-by-play plot details a secret. “There’s so many extraordinary elements throughout the movie.”

Apparently, Jake will be speaking with a British accent in the film and has been using his accent even when he is not on the movie set for practice … but unfortch (or fortch, I’m not quite sure yet) he did not use his fake British accent in this interview with ET.
