Kaley Cuoco just copped a public serve from her Big Bang Theory co-star and ex-boyfriend Johnny Galecki – on her birthday, no less.
Cuoco celebrated her 35th birthday this week, and Galecki, 45, marked the occasion with a tongue-in-cheek Instagram tribute to the woman who played his wife on Big Bang.
Alongside a selection of photos of the pair on red carpets and behind the scenes over the years, Galecki wrote: "The happiest 74th birthday to my fake wife @kaleycuoco. You know how much I adore you and respect you. I'm so proud of all you are doing and so happy with your happiness. But most of all, our friendship and partnership over the years. XO, dear. Congratulations on 82 years of age."
Cuoco took the cheeky jabs at her age with good humour, writing under the post: "THIS IS EVERYTHING! I LOVE U MOOKS! Even at my old age of 82!"
