There's something strange about turning 30. How it just creeps up on you - out of NOWHERE. How it officially heralds the end of your teenage years (don't know about you, but my twenties were a "lost" decade, so it seemed I went straight from 18 to 29 in a flash) and makes you reevaluate your life choices to date. And then the big day happens and the world doesn't implode. Nothing changes. But there's never any harm with a bit of introspection. 

Kaley Cuoco, who split up with her husband of approximately 2 years, also has that to think about on her 30th birthday - but she's focussing on more positive things. She spent her birthday at the Black Jaguar-White Tiger Foundation’s sanctuary in Mexico. 

Posting to Instagram a matter of hours ago, she said: "Today was the best birthday I have ever had ... Thank you for all the love and best wishes .. My heart is overwhelmed with joy and complete contentment. there have been a few bumps along the way, but thank you God, nothing I can't handle.. Thank you to my precious little angels who accompanied me on this trip and gifted me with something so special (they know what I'm referring to) thank you to Eddie @blackjaguarwhitetiger @paulcheca for showing us your beautiful sanctuary- how you have saved these animals from abusive , confined lives and now they are living a life they never could have dreamed of..you are the reason this planet will change... #30isgonnarock."
 


According to Us Weekly, Kaley split from Ryan Sweeting after 21 months of marriage because he couldn't commit to getting sober: "she split from the tennis pro after 21 months of marriage because she could no longer tolerate his abuse of alcohol and prescription pills. 'She supported him,' the insider previously told Us. 'But she said he couldn’t make the commitment to get sober. He’d tell her he was working on it, and instead go get wasted'."
