Actress Kaley Cuoco put on a brave face on Saturday (09Jan16) as she hit the red carpet two days after losing her beloved rescue dog Chester.

The Big Bang Theory star posed for photographers at The Art of Elysium's annual Heaven charity gala in Los Angeles, but it was clear she wasn't her usual happy self as she only cracked the odd smile for the media.

On Thursday (07Jan16), Kaley, 30, shared the heartbreaking loss of Chester, who she had adopted in October (15), with fans on Instagram.

"We rescue these angels blindly and have no idea what problems they may have," she wrote alongside a photo of her furry friend. "I'm still in shock but I just keep feeling blessed to have him in my life even for a small amount of time."

It was Kaley's latest dead doggy dilemma after losing her family pet Petey just days before.

In a similar social media post, she wrote, "Anyone who knows me, knows Petey. He was basically the first dog I ever had.

"I was gifted him on my sweet 16, by my bf (boyfriend) at the time.. I was afraid I would get in trouble so I hid him in my bedroom for 3 days until my parents found out- they said I had to take care of him if I was to keep him, that he would be mine!"
