Seemingly putting her failed marriage behind her, "The Big Bang Theory" star Kaley Cuoco appeared in high spirit as she celebrated her 30th birthday on Nov. 30, Monday.

The actress spent most part of the day with 12 of her closest friends at a wildlife sanctuary run by the Black Jaguar White Tiger Foundaion. Later, she took to Instagram to share some pics of the celebration.

"There have been a few bumps along the way, but thank you God, nothing I can't handle," wrote the actress in a lengthy caption of the pic in which she is seen overlooking the sanctuary in Mexico.

Cuoco added the hashtag "#30isgonnarock" while also thanking her friends, including former "Bachelorette" star Ali Fedotowsky, who came along for the trip. The group of girls also traveled to the famous pyramids just north of Mexico City, E! News reported.

The actress is known to be an animal lover, especially dogs and horses. Recently while speaking to ET, she referred to her pet dog, Norman, as the "main man" in her life.

The actress' milestone birthday comes two months after her surprise split from her husband Ryan Sweeting. Although she had cited irreconcilable differences for seeking divorce, an inside source told Us Weekly that the actress could no longer tolerate his abuse of alcohol and prescription pills.

The sitcom star has clearly moved on. She recently shared a pic of herself undergoing the painful-looking process of having a sizable butterfly inked on her upper back to cover her earlier tattoo that had her wedding date in Roman numerals.

"Note to self -- do not mark your body with any future wedding dates," wrote the actress to caption the picture.
