Noel Gallagher wants to move to America - but can't because of his kids. The Oasis guitarist has grown to love the U.S. as he has gotten older but can't make it his permanent home because he doesn't want his children - 18-month-old son Donovan, whose mother is Noel's long-term partner Sar MacDonald, and eight-year-old daughter Anais, with his ex-wife Meg Mathews - to have American accents.

Noel, 41, said: "I've grown to like America. It's a place for adults. Once you get past 40 you start to appreciate it.

Geri Halliwell is engaged to a man she has known for just two months. The former Spice Girls star - who has a two-year-old daughter Bluebell from a previous relationship - is set to tie the knot with shipping tycoon Fabrizio Politi, who she began dating in December after they met in a nightclub in Florence, Italy.

A spokesperson for Geri - who has previously dated singer Robbie Williams and TV presenter Chris Evans - said: "We are delighted to announce the engagement of Geri Halliwell and Fabrizio Politi."

50 Cent says he works out like a woman. The muscular rapper says his toned physique is the result of "girly" weight-free routines rather than pumping iron.

He said: "It's intense, and there are no weights involved. And some of it's like girly stuff, like just kicking your leg, but it's muscles you don't really ever work at. Men don't usually go to the gym and say, 'I'm going to develop my a*s. This'll be the J.Lo workout.'"

Geri Halliwell is dating an Italian shipping tycoon. The former Spice Girls star - who has previously romanced singer Robbie Williams and British comic star David Walliams - met multi-millionaire Fabrizio Politi at a club in Italy last month just days after she split from nightclub owner Nick House.

A source said: "It's definitely the real deal. They've really hit it off. Geri can't believe how well they get on. Fabrizio is great with her daughter."

Amy Winehouse is "addicted" to a bizarre U.K. TV game show. The "Rehab" singer is obsessed with watching BBC program "Hole In The Wall," which sees two teams of celebrities contort their bodies to fit through strange shapes cut into a giant foam wall. If they can't get through, they are plunged into a pool of freezing water.

A source said: "Amy is addicted to 'Hole In The Wall.' She reckons it's the greatest TV show she's seen in years. Obviously, this year she hasn't had the busiest work schedule so she has spent a lot of time in front of the TV."
