Aly Raisman, Colton Underwood make red carpet debut as couple

NEW YORK, Dec. 13 (UPI) -- Aly Raisman and Colton Underwood made their first public appearance as a couple Monday in New York.

The 22-year-old Olympic gymnast and 24-year-old former Oakland Raiders tight end attended the 2016 Sports Illustrated Sportsperson of the Year award ceremony for NBA star LeBron James at Barclays Center.

Raisman was all smiles in a formfitting red dress with snakeskin-like embellishment and a sheer neckline. Underwood, who wore a black suit and tie, was casually affectionate as they posed for photos on the red carpet.

"[They] looked really happy together," a source told People. "He had his arm around her throughout the dinner and they laughed a lot."

Raisman started dating Underwood over the summer after the NFL player asked her out in an online video. Her friend and fellow gymnast Shawn Johnson is married to Underwood's teammate Andrew East.

"We both happened to be in Denver at the same time," Raisman told People of their early romance. "I was there for less than 12 hours; he was flying in for just a few days. It just ended up working perfectly."

"I'm just looking forward to 2017," she gushed. "I think it's going to be an exciting year for everyone."

Raisman is a three-time Olympic gold medalist who competed in the 2012 Summer Olympics in London and the 2016 Summer Olympics in Rio. Underwood is an NFL free agent who has also been signed to the San Diego Chargers and Philadelphia Eagles.
