Kevin Richardson to be a father again

London: Backstreet Boys star Kevin Richardson is set to become a father for the second time.

The 41-year-old singer took to Twitter to announce that his wife Kristin is pregnant, reported Contactmusic.

Posting a photo of his visibly-pregnant partner, he posted, "So excited to share... The Easter Bunny brought a very special egg this year."

The couple already has a five-year-old son, called Mason.

Richardson`s second child will be the sixth born to the members of the Backstreet Boys.

Howie Dorough has two kids, Brian Littrell one and AJ McLean`s firstborn arrived in November last year.
