JEN ANISTON’s PREGNANCY SECRET

It’s a boy for Jennifer Aniston!

The former “Friends” star now goes by the name “Auntie Jennifer” after her punked-out half-brother AJ’s partner gave birth to a son.

AJ rushed a heavily pregnant Adriane Hallek to a Los Angeles hospital on December 5 when she went into labor.

When they arrived, AJ helped pink-haired Adriane into a wheelchair and whisked her inside.

The couple welcomed their firstborn about 24 hours later at the facility, which is less than two miles from Jen’s Hollywood home.

As The ENQUIRER has reported, the heavily tattooed 25-year-old is known for his free-spirited lifestyle, and living out of a battered black van while drifting between L.A. and Alaska.

He’s the son of Jen’s dad, “Days of Our Lives” star John Aniston, and his second wife, Sherry Rooney.

Pretty new mom Adriane, 25, is a model and horror movie makeup artist.

The couple started dating in January, and at one point wrote on Facebook they were “married,” although it appeared to be nothing more than a joke!

When The ENQUIRER contacted Adriane in May and quizzed her about AJ, she said: “He’s a great guy, but I don’t want to talk about him. He likes his privacy.”

Asked if she’d met her superstar soon-to-be relative, Adriane admitted: “No, I have not.”

The actress and her brother have rarely been seen together. AJ hasn’t made an appearance with her in public since 2004.

When asked about his big sister Jen’s fame in 2013, he said: “It’s been a pain in my a– for years.”
