It was like a scene right out of Beverly Hills, 90210. There was Tori Spelling, in Toronto Sunday with new Canadian hubby Dean McDermott for the MuchMusic Video Awards. So who crashes the scene but McDermott's out-of-control ex, Mary Jo Eustace.
Chatty Spelling spilled the beans to the Sun yesterday from CTV's Masonic Temple, where she was promoting her upcoming series So NoTORIous (premiering in Canada July 13 on MTV).
Spelling was bonding backstage with billionaire gal pal Paris Hilton at the time.
"Paris and I have known each other since we were little girls," said Spelling. She said Hilton was showering praise on McDermott, thanking him "for making my girl happy."
"Funny you should say that," said Spelling, "because the ex-wife is here and her friend is screaming home wrecker over there."
The friend? Eustace's former cooking show co-host, Ken Kostick.
"
And then Paris," continued Spelling,
"in very Paris style, looked over and said, 'F---, that's pathetic.'"
Eustace, who's shopping a book about her messy marital bust up, crashed the MMVAs with Kostick. She told Canadian Press that at one point she was tossed from the CHUM/CITY building when security told her there was a restraining order against her.
Fortunately, no finger nails were broken at the event. Spelling said she had no direct contact with Eustace, who had told her ex-husband she was up north at a cottage for the weekend with their seven-year-old son, Jack. Spelling said the ex ambush kind of wrecked Father's Day, but that's showbiz.
Otherwise, how was the party? Spelling said she had a blast at the MMVAs. "It's so much better than (U.S.) award shows," she said. "Ours are so formal and structured; everyone is kept away from you. Here it's loose, everyone's just walking down the red carpet ... the fans are all on top of you ... you don't feel so separated." Well, unless you're the ex-wife.
