The Backstreet brood continues to expand!
After celebrating their 20th anniversary over the weekend, the boys — A.J. McLean, Brian Littrell, Howie Dorough, Kevin Richardson and Nick Carter — gathered to unveil their star on the Hollywood Walk of Fame on Monday in Los Angeles.
Joining Richardson, 41, at the ceremony was wife Kristin — whose pregnancy was announced last week — and their son Mason, 5½.
This will be the third Backstreet baby in the past year — Dorough welcomed son Holden in February while McLean welcomed daughter Ava in November.
