“Friends” alum Jennifer Aniston is pregnant with twins, OK! magazine claims on the cover of its latest issue. It’s not the first time rumors swirled that the beloved actress was with child, but she reportedly underwent in vitro fertilization treatments for over a year before she learned she was pregnant.

Aniston, 46, discovered the happy news shortly before her wedding to Theroux, 44, an actor and screenwriter. (The began dating after co-starring in the 2012 comedy "Wanderlust.") “She cooked him a romantic dinner, and afterward, she told him that she had a special surprise. Then she showed him the test results. He was very emotional -- he actually cried a little! Jen was so touched,” an insider told OK! magazine, according to Hollywood Life.

The actress didn’t find out she was having twins until later when Theroux was filming a movie in Texas, the source said. Since they weren’t together she sent him a cheeky text “with a picture of the ultrasound and joked that they were going to have double trouble,” the source said. The “Cake” actress was thrilled with the news and became “even more excited” about the pregnancy.

Both of the babies are girls and Aniston wants to name one of her daughters Ava after Hollywood icon Ava Gardner; Lila is another favorite, OK! magazine reported. She still has time to decide on names, though. Aniston is only three months into her pregnancy.

The cover of the magazine features a picture of the Emmy-winning actress smiling widely. OK! refers to her pregnancy as an “IVF miracle.” There is also a picture of an ultrasound, though it was not confirmed it was an authentic one belonging to Aniston and Theroux. One of the bullet points claims Theroux cried when he found out about the pregnancy.

Neither Aniston nor Theroux have responded to the pregnancy rumors. Don’t be surprised if the gossip turns out to be nothing more than fabrication. It was once rumored that Brad Pitt, who was once married to Aniston, left her for Angelina Jolie because the “Friends” star didn’t want to have children. He and Jolie now have six kids.
