Family affair! Kelly Rowland can't hide her smile as she arrives at US Open with son Titan and husband Tim Witherspoon

Kelly Rowland welcomed her little bundle of joy this past November, and it seems the star is thrilled to be able to bring young Titan Jewell Witherspoon along as she hits high profile events like the US Open.

And on Sunday the 34-year-old did just that, sporting a big grin as she toted Titan while arriving to day seven of the tennis competition.

The new mom - who was also joined by her husband, Tim Witherspoon - showed off her enviably lean legs in fitted denim shorts as she made her way into the Billie Jean King National Tennis Center in New York City.

Kelly looked casual but stylish as she arrived sporting a loose-fitting white tank top, which showed off the singer's toned arms.

She coupled the top with a pair of form-fitting distressed shorts, which emphasized her slender legs, and topped off the chic look with a black fedora.

She accessorized with a long, gold necklace and coordinating bracelets on each arm, and hid her eyes behind a pair of black, round-framed sunglasses.

The former Destiny's Child member showed off a bright red manicure, and wore her long, raven tresses in loose curls. 

Kelly showed off her pearly whites as she sported a wide smile while carrying her son Titan, who wore a bright orange short-sleeved T-shirt and patterned blue shorts.

The doting mother held her little boy up for the cameras, clearly happy to be out with her pride and joy, before she handed him to his father for a few photos.

She smiled and waved to fans as Tim, who matched her casual style, was then spotted doting over the tot.

He wore a fitted grey, short-sleeved T-shirt with distressed, light wash jeans, and a black snapback hat which read, in bold white lettering: 'Save Art.' 

The couple - who tied the knot in May 2014 - kept close together, along with son Titan, as they made their way into day seven of the competition.
