R&B singer Monica and her husband Shannon Brown are expecting their first child together.  Over the weekend, Brown took to Instagram to show off Monica's baby bump. 

Monica's bump can be seen through a blue gown she's wearing as she and Brown walk arm-in-arm.  In a caption accompanying the pic, Shannon expressed his joy, writing "Hallelujah" and "I'm so blessed."  After Monica reposted the picture on her Twitter feed, she was inundated with messages from fans wishing her the best.  Monica thanked her fans and revealed that she is five months along.  

Both Monica and Shannon Brown - who married in 2010 - have children from previous relationships.  Monica had two children with rapper Rocko before their relationship ended in early 2010.
