The Saturdays' Rochelle Humes Is Pregnant!

British pop star and hubby Marvin Humes are expecting their first child together

Rochelle Humes (née Wiseman) is gearing up for diaper duty!

The 23-year-old singer for the U.K. girl group The Saturdays is just giddy after learning she's going to have her first baby. 

Rochelle tells E! News exclusively that "this year has been full of incredible moments, including getting married, but finding out I was pregnant was by far the best moment of all."

Just a month ago, Rochelle told the Sunday Mirror that seeing her fellow bandmate Una Healy successfully juggle life as a mom and a performer gave her some inspiration.

"I'm really looking forward to falling pregnant," she told the mag. "Una's proved being a mother and being on the road can work.'

This is the first child for the British pop star and her JLS singer hubby, Marvin Humes, who wed in July.

Congrats!
