Ryan Sweeting will take care of Cuoco: `Big Bang` co-star Kunal Nayyar

Los Angeles: English-born Indian actor Kunal Nayyar feels that his `Big Bang Theory` co-star Kaley Cuoco`s husband Ryan Sweeting will take good care of her.

The 32-year-old actor plays astrophysicist Rajesh Koothrappali in the comedy show, reported People magazine. "Ryan Sweeting is a great guy and I know he`s going to take great care of her. I think they both complement each other really well," Nayyar said. "I think the beauty of their relationship is they don`t take anything too seriously. They`re always laughing, which is really important in a marriage. Hopefully they`ll keep each other in check," he added. Cuoco tied the knot with Sweeting on New Year`s Eve in a fire-and-ice-themed ceremony. Nayyar, who called the New Year`s Eve nuptials "a really, really great night," felt honoured to be a part of experience. "Kaley is like a sister to me. You become so close over such a long period of time. It`s like your family member getting married," he said.
