Birthday with bae! Kaley Cuoco stepped out in West Hollywood on Wednesday night to celebrate her 31st birthday with her boyfriend, Karl Cook.

The pair were spotted holding hands while making their way to celebrity hot spot Craig’s. The Big Bang Theory star wore black leather leggings and a matching jacket with her long blonde hair down.

Her boyfriend rocked a pink and blue plaid jacket with jeans.

Cuoco has been spending lots of time with her man lately, posting a cute pic to Instagram earlier this week sitting in between him and her English bulldog with the caption, “I can’t choose.”

She recently opened up to Women’s Health magazine about first meeting Cook, saying, “Literally, we bumped arms at a horse show. We each said, ‘Oh, I’m sorry’ -- and everything changed. I looked at him and he looked at me...”

The CBS star also posted a throwback group shot to Instagram with her gal pals from her blowout 30th birthday, writing, “This time last year I was with 12 of my best gfs on the birthday trip of a lifetime in Mexico City visiting @blackjaguarwhitetiger. An adventure I will never forget!!!!! Love you girls!!!!”

It was also her younger sister Briana Cuoco’s birthday on Monday and Kaley posted a goofy pic with the caption: “It’s your birthday @bricuoco!!!!!!!!! The best sidder in all the land. I love you forever!!! Happy birthday!!!”
