Sources tell TMZ that the newlywed couple are expecting a baby girl, which is behind their choice of a pink-themed wedding in Jamaica. Rebelo, 29, is reportedly four to five months along. It's the couple's first child together, but both of them have had kids in previous relationships. Jeremy already has three children in Justin, Jaxon, and Jazmyn from two previous marriages, while Rebelo is mother to her daughter, Allie.

With a new child on the way, the pair will be having a short honeymoon period. Jeremy and Rebelo brought their families together in Jamaica for a beautiful outdoor wedding. Set against the stunning natural backdrop, it was an intimate affair with only 30 guests watching as they said their vows. From photos posted in social media, the wedding seems to be a laid-back event with the groom and his groomsman, Justin, in pink shorts. The bridal party wore flowy white dresses that looks perfect in the outdoor affair.

While Jeremy's superstar son was part of the wedding party, Justin reportedly opted not to perform or give a toast in front of all the guests.

Of course, the famous guests of the wedding are Justin and on-again girlfriend Gomez. E! News reveals Justin picked up his ladylove from Dallas, Texas, in a private jet, and then the two flew to Jamaica together.

The couple enjoyed the romantic getaway along with the rest of the Bieber family. Gomez is close to many of the family members, even taking selfies with a few of her beau's cousins.

A source even dishes that the romance in the air is getting to Justin, who has begun to think of the future as he watched his father tie the knot.

"Justin's really inspired right now and that has not only sparked new music from Justin, but personal conversation with his loved ones as well," an insider shares to Hollywood Life. "Justin and Selena have been having discussions about their future together and they can absolutely see a life where they are married and enjoying kids together."
