Jennifer Aniston fueled pregnancy rumors at the Oscars on Sunday after the actress and Justin Theroux took a suspicious pose on the red carpet, which many took to be a hint that she is expecting.

Aniston and Theroux are currently engaged to be married, denied that they were expecting a baby girl back in November. The couple arrived hand in hand at the 85th Academy Awards in Hollywood and posed together for the mass of photographers at the event.

However, at one point Theroux, 41, placed his hand on Aniston's stomach and caressed it, sparking a social media frenzy among fans on Twitter.

"If Jennifer ISN'T pregnant, that was a very bizarre pose on Theroux's part. Congrats to the happy couple in advance #obviouslypregnant," Kaye tweeted.

"Did anyone catch Justin's hand on her stomach? OMG Jen Aniston's so pregnant!" Tamara tweeted.

"I hope Jennifer Aniston is pregnant...she looks b----- amazing! She's a little less toned and a little fuller...glowing! ;)," Lauren Jones tweeted.

The pregnancy speculation follows recent reports claiming that the former "Friends" actress is pregnant with twins.

"Jen's feeling giddy with excitement right now. She's dying to tell the world her amazing news," a source told OK! Magazine.

"She never imagined that at this age she'd be planning to be a first-time mom with twins!" the source added.

The couple held a star studded bash for an engagement party in Los Angeles in December, and sources claimed that Aniston, 43, showed signs of being in the early stages of her pregnancy.

One source claimed that the actress refused to drink alcohol and raw fish during the party.

"They had a margarita bar, but she didn't go near it, opting for water instead. It was so unlike her and didn't go unnoticed," a source previously told Grazia magazine about the event.

"She was also picky with what she ate, and didn't touch the huge sushi platter, which is one of her favorite foods," the source added.
