Jennifer Aniston and Justin Theroux are reportedly trying to have a baby, again.

"Jen is currently exploring the surrogate option," an alleged source told In Touch magazine. "Of course, she'd still love to get pregnant naturally, but she's under no illusion that it would come easily, as she turns 45 on Feb 11. Surrogacy is the perfect solution."

The We're The Millers star and her fiancé have reportedly taken this route because Aniston became impatient while trying to conceive naturally. The website also claims that the couple was able to talk about their family plans when they vacationed in Mexico during the holidays.

"The holiday was an opportunity to spend quality time together and discuss their future and plans for a family," a source close to the actress also told inTouch. "Now, they are investigating finding the right candidate to carry their child."

This new report is just one of many that claims Aniston and Theroux are trying to start a family. Last September, Aniston's publicist even stepped in to slam rumors that she was expecting.

"Jennifer is NOT pregnant and their story is just another fabrication," Stephen Huvane told E! News in regards to a Us Weekly cover at the time.

The former Friends star even previously revealed her frustration with the ongoing pregnancy rumors.

"It does feel like they've exhausted the question, and also the speculation. It's all been pretty much exhausted," Aniston said during an August 2013 interview with Australia's Kyle & Jackie O Show.

"Why not just wait until we actually get to have the fun of announcing something? Who wants to play the guessing game?"
