JEN ready to bare ALL as pregnancy dreams just…fade away.

AFTER failing to con­ceive with her fiance Justin Theroux, Jen­nifer Aniston is finally giving up on her dream of getting pregnant and instead refocusing on her career, say sources.

In fact, the former “Friends” beauty is said to be considering going topless in the sequel to her hit comedy “We’re the Millers.”

“If Jennifer thought there was any chance that she’d be getting pregnant, there’s no way she’d prepare for a project in which she’ll have to strip down,” said a source. “The truth is that Jen and Justin have been trying all year to conceive with no luck.

“She tried every fertility treatment available, which is why she packed on the pounds over the summer and was sporting what some people thought was a baby bump at the New York premiere of ‘We’re the Millers.’”

Jennifer, 44, recently changed her looks by chopping off her trademark locks – and now she’s said to be wrestling with an image makeover.

“Jen’s completely torn over the prospects of going topless because she’s made $45 million from her ‘America’s Sweetheart’ persona,” a longtime friend of the actress told The ENQUIRER. “But with Justin encouraging her to go for it, she’s serious­ly considering revealing her breasts in ‘Millers 2’ before she gets too old!”

An insider says that Jen has all but signed on to reprise her role as stripper Rose, and that she wants filming to be done in six months – as soon as pos­sible after she wraps “Horrible Bosses 2.”

“Jen’s in her best shape ever and can’t wait to show it off,” revealed the source. “She says she loved playing a stripper in her 40s, and Justin’s been urging her to get edgier with her roles.”

Still, Jennifer is said to be weighing various options to keep it tasteful.

“It’s possible the topless shot will be from a distance and Jen will be wearing a body stocking or even body art, but she’s also discussed with the studio the possibility of a close-up with her breasts pixilated or covered with a funny blooper motif,” noted the source. “She thinks that could be funny but still provocative.”

Meanwhile, Jennifer and Justin have not been seen together in public recently, sparking whis­pers that the two are drifting apart.

But her pal says that they are just immersed in their careers and are still committed to each other – and even to starting a family someday.

“Since they haven’t been able to conceive naturally, Jen and Jus­tin are now looking at adoption or hiring a surrogate,” said the source. “She’s not going to let anything get in the way of starting a family with Justin.”
