After 16 years of on-and-off dating, the Sugar Ray frontman, 42, and Kingsland, 37, an aesthetician, became engaged last New Year s Eve and confirmed in April that they were expecting twins thanks to IVF.

“These two kids will be the luckiest kids in the world in terms of their mom, that s for sure,” says McGrath, who will host Fox s Don t Forget the Lyrics! this fall and tour with Sugar Ray in the summer. “They ll get a lot of love. ”

In fact, he jokes, it may feel like Kingsland has three little ones once they get home. “Carin has taken care of me for the last 16 years,” says McGrath, “[Lydon and Hartley] are going to have trouble playing with their toys because I ll be using them all the time!”
