Justin Theroux rode his bicycle through Manhattan this week while rumors continue to suggest that he and his fiancé Jennifer Aniston are expecting their first child.

Justin Theroux Bikes In NYC

Theroux, 42, hit the sit streets on Wednesday in gray skinny jeans and a tight black t-shirt that matched his black leather sneakers, and he accessorized with a pair of gold-rimmed aviators. His bike, with its yellow frame, stood out distinctly from the actor’s gray and black ensemble.

While Theroux appeared carefree on his bike ride, he might soon be adding fatherhood to his list of responsibilities, according to recent reports. “[Jen's] a little more than three-and-a-half months along and just found out the baby’s sex,” a source told HollywoodLife.com. “It’s incredible news for the two of them. Just a few months ago they were on the brink of splitting.”

“[Jen's] telling friends this is a miracle baby. She’d pretty much given up on conceiving naturally,” the source added.

Both Theroux and Aniston have been busy as of late working on their current projects. Aniston has been in L.A. filming Cake with Anna Kendrick and Sam Worthington, while Theroux has been working on new HBO sci-fi series The Leftovers in which he plays chief of police Kevin Garvey, who's left behind with a number of others after a rapture.

The Leftovers premieres June 29.
