Put those divorce rumors to rest.

Tori Spelling and husband Dean McDermott are renewing their vows, a rep for the couple confirms exclusively to

The two -- who have two children, Liam, 3, and Stella (who turns 2 next month) -- celebrate their four-year anniversary Friday.

Spelling, 36, and McDermott, 43, have battled split rumors this year as footage from the fifth season of their hit Oxygen show Tori & Dean: Home Sweet Hollywood shows them in heated spats.

On one episode, she yells at him, "It's like you got more and more unhappy and angry. I just want the old Dean back. I really do. I miss you so much." During another fight, he even drops the F-bomb because she feels he is not being ambitious enough about his career.

Just because they fight doesn't mean they're heading to divorce court, she has said.

"Everyone has marital problems," Spelling said on The Ellen DeGeneres Show last month. "You know, you fight with your partner."

She also squashed split rumors on the Today show: "We have our fights. We have our ups and downs. It's a real relationship. Some issues have come up this season, and the cameras were there to catch it. And I'm happy to put that out there to my fans, because we're a normal, relatable couple. We're not perfect, and things happen."
