Jennifer Aniston Kicks Off the Work Week

Showing off her gorgeous gams, Jennifer Aniston was spotted kicking off the work week in New York City on Monday (April 27).

Continuing on with the filming of her new movie, the former "Friends" actress looked a bit tired as she joined her co-stars to shoot scenes for "The Baster".

Meanwhile, it sounds as if Miss Aniston has upset singer/actress Jennifer Lopez as a result of her role as a woman trying to get pregnant in "The Baster".

"The last thing J-Lo wants is to have Aniston overshadow her," a source tells the Daily Mail. "There’s been some mud-slinging, with J-Lo claiming Jen took her idea."

Jennifer Aniston: Furious with John Mayer?

Spending the day working on her new movie, Jennifer Aniston offered up a smile while filming "The Baster" in New York City on Tuesday (April 21).

And while the former "Friends" starlet appeared to be in high spirits, recent rumors tell that Jen is "furious" with ex-beau John Mayer as a result of him calling her "needy".

According to a tabloid insider, “John’s been recording in a studio and coming on to almost every woman in the vicinity. He goes on and on to these women about how clingy and needy Jen is. He says that when they got back together after their first breakup last August, it was agreed she would back off on the smothering."

The source adds, “When someone tries to change the subject, he goes back to Jennifer, claiming she was so emotionally dependent and demanding that he couldn’t take it. Jen ended it with John because of his wandering eye blabbing about their love life, putting career before love - and refusing to live full time with her or put an engagement ring on her finger. In the end, his immaturity was just too much for her.”

Meanwhile, the latest tabloid fodder tells that there's concern over Jen's eating habits - as on-set spies tell that she doesn't seem to ever be seen stuffing her face.

The insider tells, "She doesn't seem to eat anything. She's constantly sipping water but no one has seen her actually eat. In fact she looks like she's lost a lot of weight - almost to the point that she looks unhealthy."
