Tori Spelling reveals which of her famous friends inspired her to finally move on Dancing with the stars.

Spelling sat down with PEOPLE on Wednesday, September 4, after it was announced that she would be joining season 33 as Pasha Pashkov’s partner. The actress admits that she always doubted her ability to compete on the dance competition show and says she’s excited.

“I had been offered it before and I really wanted to do it – I’m such a huge fan – and I was just too scared to ever say yes,” she admits.

This time, Spelling, one of her Beverly Hills, 90210 Her co-stars encouraged her to accept the challenge.

“Brian Austin Green knew the whole time I got that call,” she says. “So I kept thinking, ‘I don’t know if I should do it or not,’ but he was like, ‘You’re going to be great, you have to do this.'”

The Troop Beverly Hills Alum’s connection to Green, who appeared in season 30 of DWTS with her fiancée Sharna Burgess was also a reason for her to join the show. Spelling says she hasn’t gotten any dance tips from Burgess yet, but she has consulted her while she waited to find her partner.

“From the beginning, I asked, ‘Sharna, who do you think I’m going to get as a partner?'” Spelling explains. “And she literally looked through all of them and said, ‘He’s great and he would work for you,’ and when she told me everything, she was like, ‘This one would be perfect for you,'” Spelling continues, pointing at Pashkov.

“So when I walked in (and saw Pashkov), I thought, ‘Oh my God, Sharna was right!'” she adds.

In addition to Spelling and Pashkov, this season’s cast includes Real Housewives of Atlanta Star Phaedra Parks dances with professional Val Chmerkovskiy (brother of Parks’ The traitors co-star Maksim Chmerkovskiy); Oscar nominee Eric Roberts (brother of Julia Roberts and father of Emma Roberts) starred with Britt Stewart; and convicted con artist Anna Delvey was with Ezra Sosa.

Other contenders for the Len Goodman Mirrorball Trophy include NBA champion Dwight Howard, dancing with Daniella Karagach; former NFL wide receiver Danny Amendola, dancing with Witney Carson; Sports Illustrated Swimsuit Model Brooks Nader in a duel with Gleb Savchenko; Olympic rugby player Ilona Maher in a duel with Alan Bersten, The Bachelor‘S Joey Graziadei, who will dance with Jenna Johnson; Pretty Little Liars: Summer School Star Chandler Kinney paired with Brandon Armstrong; Family matters Patriarch Reginald VelJohnson worked with Emma Slater; and The BacheloretteJenn Tran, fresh from her finale, dances with Sasha Farber.
