It will be a girl for Kevin and Danielle Jonas.

The Jonas Brothers singer and his wife are expecting a daughter, they revealed Thursday.

The "Married to Jonas" stars shared the news by posting an ultrasound photo on Instagram, with a pink bow added to the little one's head.

"It's a girl!!!!! Thank you everyone!! She's sucking her thumb!" Jonas wrote.

His mother, Denise, also chimed in on Twitter: "After years of testosterone-Finally estrogen! I am so blessed to have a granddaughter!"

The parents-to-be, both 25, announced the pregnancy in July. They wed in 2009.
