The man seen in this screenshot is a member of which American boy band?

The man in the image is Brian Littrell (born February 20th, 1975), one of the five members of the Backstreet Boys, as seen in the music video for their 1997 smash hit, "As Long As You Love Me". The other four members in the group are Howie Dorough, AJ McLean, Kevin Richardson, and Nick Carter. Kevin is the oldest of the five men and is Brian's cousin, and Nick is the youngest, being the only one born in the 1980s.

The Backstreet Boys are considered one of the most consistent and popular boy bands of the '90s and early 2000s with hits such as the aforementioned "As Long As You Love Me", "I Want It That Way", "Larger Than Life", and "Shape of My Heart". Despite never having a #1 song in the USA, BSB have globally sold 100 million copies, making them the best-selling boy band of all time, and are also the only one of that kind to have their first ten albums make the Top 10 of the Billboard 200.
