Singer Kelly Rowland is expecting her first child with her new husband and manager Tim Witherspoon.

The `Motivation` hitmaker confirmed the news via Instagram Tuesday by posting a photograph of Witherspoon's sports shoes alongside a matching baby pair, with the caption: "I'll be stuntin like my daddy... (sic)."

A source close to the star also confirmed she is pregnant, reports people.com.

Rowland, 33, first sparked rumours she is expecting when she and her husband were spotted shopping at upmarket baby store Bel Bambini in West Hollywood last month.
