Britney Spears is buying a $22,000 oxygen chamber to protect her voice. The "Womanizer" singer - who reportedly lip synchs to her songs during performances on her current world tour - is set to splash out the sum because she is terrified of "bad air" ruining her career.

The move comes after Britney stormed off stage in Vancouver, Canada, because the arena was too smoky last month.

Megan Fox has moved into Britney Spears' old apartment building. The "Transformers" actress and boyfriend Brian Austin Green are living in a stunning $10,000-per-month property in California which overlooks the pacific ocean and boasts 24-hour valet and room service, personal trainers and private elevators.

A source revealed to RadarOnline: "It's a very exclusive address and the staff are used to dealing with celebrities and being discreet."

Leona Lewis has fled her U.S. mansion after fearing she was being stalked. The "Bleeding Love" singer - who only moved into the $6 million Hollywood property last week - has returned to the U.K. after being left shaken when she was followed home from the shops by a man.

A source said: "Leona was completely unsettled by this and was pretty relieved to get back to the house safely. But when she looked out of the window later the man was still there, staring right at her. It freaked Leona out big time. She feared she was being stalked."

A source said: "Britney loves pole dancing, it is her new favorite work out. She gets the toning she needs without having to hit the gym and wants to do it in the privacy of her own hotel room."

Jamie Lynn Spears' boyfriend has taken his first steps after suffering head injuries in a car accident. Casey Aldridge - the father of Jamie's 10-month-old daughter Maddie - has been released from intensive care and is walking again, just days after he crashed his vehicle on Sunday.

A source said: "He came out of ICU (intensive care unit) and was walking around twice on Tuesday. He was a little wobbly because that's the first time he's been up since the wreck."

Jennifer Lopez finds staying at home "sexy." The singer-and-actress - who has 14-month-old twins Max and Emme with husband Marc Anthony - likes nothing better than snuggling up with her man for a quiet night in, despite her glamorous lifestyle.

She said: "People will probably be surprised to discover that I find it sexy to stay home - to me that's the best place to be. I find it really cozy and yummy being with a man who loves to stay in."
