Kaley Cuoco celebrated her 30th birthday at an animal rescue sanctuary.

Teasing the trip over the weekend, Kaley wrote on Instagram: "2 planes, 12 best friends, one 30th bday, destination unknown = priceless," before later revealing her destination with a post which read: ""Starting off my 30th year with a roar ... Surrounded by my best friends and all the lions and tigers I can count (sic)."

Kaley also shared a picture of herself with Black Jaguar White Tiger founder Eduardo Serio and wrote: "Epic Eddie #badassdude #ouralbumcover @blackjaguarwhitetiger #dirty30 #savingtheworldonerescuecatatatime (sic)."

According to its website, the foundation has rescued "over 180 (and counting!) Big Felines including Jaguars, Tigers, Lions, Leopards, Lynxes and Pumas from a life of abuse in circuses, zoos and illegal breeders".

Meanwhile, Kaley's birthday trip comes over two months after filed for divorce from professional tennis player Ryan Sweeting after less than two years of marriage.

And Kaley recently revealed she is "incredibly grateful" for the support she has received since splitting from Ryan.

She said: "I'm feeling completely overwhelmed with the outpouring of kindness and support from the people that surround me and from those I have never even met.

"I want you to know, I read all your comments and your sweet words have touched me deeply.

"I'm incredibly grateful for all your love as I start this next chapter in my life."
