Jennifer Aniston will have a daughter!

Jennifer Aniston is pregnant! According to the cover of America’s In Touch Weekly magazine, the actress is suffering with morning sickness, crazy cravings and rapid weight gain.

Sources say Jen has been having fertility treatments for years — and her fiance Justin Theroux is giving her neck massages!

Jennifer has riled Justin by flirting with her Cake costar, Sam Worthington.

Jen and Sam’s chemistry is white-hot on and off the set – and the rugged Australian has been meeting with Jennifer in private.

“Jennifer is insisting that she’s just good friends with Sam, but Justin is acting like a jealous teenager”, an insider said.

“She’s told him to chill – and that Sam is deeply in love with his girlfriend (Australian model Lara Bingle) – but Justin keeps grilling her about Sam and it’s really getting on her nerves”.

Meanwhile, Jennifer and Justin — who got engaged in 2012 — are struggling to plan their wedding.

“Jen is the most indecisive woman on the planet”, said a source. “She’s changed her mind a million times about everything. Jennifer has been dreaming about a fairytale wedding to Justin. But it just keeps eluding her grasp”.
