Happy Birthday, Tori Spelling! The mother of four took to her Instagram account to share adorable photos with her two eldest kids, celebrating her 41st birthday on May 16.

Spelling, who has had a rough year, which she's documented on Lifetime reality series True Tori, first shared a picture of herself and son Liam, 6, smiling over a plate of cupcakes and treats with candles in them.

Spelling captioned the pic: "My first bday celebration," giving a shoutout to good friend Mehran Farhat, who presumably helped Liam with the surprise.

A second photo shared by the author included Liam and eldest daughter, Stella, 5, with the caption: "A birthday donut from my babes... #happymama."

A source tells Us the reality star is planning on continuing her birthday celebrations with friends while on the set of her new show, Mystery Girls, today.

Spelling's estranged husband, Dean McDermott, is out of the country in Canada
