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.
