Big Bang Theory star Kaley Cuoco appears to be really happy lately ? and it?s probably thanks to her new boyfriend, equestrian Karl Cook. The actress took to Instagram on Friday to share a sweet photo of her cuddling up to Cook. Alongside a heart emoji, Cuoco wrote, "That?s what happy looks like." The new photo comes one week after the couple made things official with a kiss on the beach and Cuoco has posted multiple photos of them looking very cozy over the last month.
