Posting a picture of his expectant wife caressing her baby bump, the Backstreet Boys band member joked, "The Easter Bunny brought a very special egg this year!" The couple, already parents to 5-year-old son Mason, met in 1993 and have been married since 2000.

This will be the sixth child born to a member of the pop quintet: Brian Littrell has one son, Baylee; AJ McLean has one daughter, Ava; and Howie Dorough has two sons, James and Holden. Nick Carter, who has no children, proposed to fitness expert and actress Lauren Kitt in the Florida Keys on Feb. 20.
