Tori Spelling Shares 'Little Known Fact' About 'Cult Classic' Christmas Flick

Tori Spelling recently opened up about a “little known fact” regarding her personal circumstances when she filmed the TV movie The Mistle-Tones more than one decade ago.

The movie has become "a cult Christmas classic on everyone’s must watch list every holiday season” since its premiere on ABC Family in December 2012, Spelling explained in an Instagram post on Monday, Dec. 9. The Beverly Hills, 90210 alum said her starring role in the holiday musical was “one of my favorite projects,” though she guessed those who watched the movie at the time it premiered likely didn’t know what was going on with Spelling’s family as she was filming it.

“Little known fact was that my 12 year old Finn starred in this movie too,” Spelling, 51, shared. “I had my newborn Hattie and was 8 weeks pregnant with Finn when we made this movie but it was a ** SECRET** I didn’t share with anyone.”

Spelling’s eight-part Instagram post kicked off with a promotional image created for the movie, which showed Spelling looking directly at co-star Tia Mowry as a large microphone was positioned between them. Subsequent screenshots from the film and behind-the-scenes photos showed Spelling and other members of the cast as they worked on the film.

“If you look close you might be able to see my baby bump,” Spelling informed her Instagram followers.

At 12, Finn is the second-youngest child that Spelling shares with Dean McDermott, who she is in the process of divorcing. The two also share sons Liam, 17, and Beau, 7, and daughters Stella, 16, and Hattie, 13. McDermott has another son, 25-year-old Jack, from a previous marriage.

Spelling concluded her Monday Instagram caption with a special pitch for Mowry. After tagging the Sister, Sister star’s Instagram account in the post, Spelling asked, “when are we making the sequel? Snowbelles next generation 🎄♥️.”
