Kelly Clarkson wants a ''big family.''

The 32-year-old singer welcomed her first child, daughter, River Rose into the world with her music manager husband Brandon Blackstock in June and is already thinking about expanding her family.

A source said: ''Don't expect River to be their only baby as Kelly and Brandon want a big family.''

The 'Stronger' hitmaker is enjoying spending time with her little girl, but is reportedly missing her music career and is eager to get back on stage as soon as possible.

The source explained to RadarOnline.com: ''Kelly is loving every single moment of motherhood. Being a mother is something Kelly has always wanted, so this is truly a dream come true for her. But it doesn't take away from the fact that she's a singer and an entertainer and misses it.

''Kelly is eager to return to the stage, but her focus is one million percent on her family right now.''

The stunning star married Brandon, who has two children from his first marriage, Seth, seven, and Savannah, 11, in a low-key ceremony in Tennessee last October and previously admitted she couldn't wait to have her own children with her beau.
