She got engaged after a whirlwind three-month romance and now it looks like Kaley Cuoco could be getting broody.

The 37-year-old actress and her fiancé Ryan Sweeting were spotted cooing over an adorable baby at a charity event in Griffith Park in Los Angeles on Sunday.

While Kaley cuddled the infant, the tennis player looked on adoringly at them both and patted the baby’s head.

The couple were attending the 16th Annual ‘Walk and Roll’ to benefit the foundation Shane’s Inspiration, which works to build playgrounds for children of all abilities on the West Coast.

Kaley served as Grand Marshal for the event and couldn’t have looked any happier.

The Big Bang Theory star is clearly still on a high from her recently engagement and sported a huge smile as she got proceedings off to a start.

Dressed casually in skinny jeans, flat sandals, a cream sweater and a khaki green jacket, Kaley mixed up her look with two different hats, a beige baseball cap and a blue trilby.
