Open Mic Music Call

It's a big week for rock and roll babies. Yesterday, Lights and husband Beau Bokan of Blessthefall announced the birth of their daughter, Rocket, and, now, today, Fall Out Boy's Pete Wentz and girlfriend Meagan Camperhave announced that they are expecting.

Rocket Wild Bokan, the Bokans' first child, was born early Saturday morning. The couple first announced that they were expecting back in the fall, and have been married since May 2012.

Blessthefall will hit the road this spring, with support from Silverstein, The Amity Affliction, Secrets, and Heartist. Lights and her hubby were recently named one of our "10 Essential Rock Couples."

Wentz and Camper, who have been dating for nearly three years, also took to Instagram to announce their pregnancy. Wentz has one other child, a five-year-old son named Bronx Mowgli Wentz, from his previous marriage to Ashlee Simpson. In a recent interview with Us Weekly, Pete mentioned that he and Meagan, who works as a model, were considering plans to marry, though the couple have not yet announced a formal engagement.

Wentz and the rest of Fall Out Boy will next tour Europe and South America, before heading out for a summer co-headlining run with Paramore.
