90210 is always full of surprises, but TVLine's Michael Ausiello spilled something that just might take the cake. According to the spoiler king, Annie (Shenae Grimes) becomes a professional escort (!) sometime in Season 4.

While she's busy gettin' busy, Navid (Michael Steger) takes the high road and cleans up his father's porn business. "What I do [with the business] is different. How I legitimize my father's porn company is by just cleaning house," Michael Steger dished to E! Online. "I get rid of every attachment I have with my father and we are producing music videos, training films, shooting commercials. Navid is already making a huge sacrifice. He moved in with Silver, sold his car and he is putting all of his money toward his business."

On top of that huge responsibility, Navid finds himself in charge of his kid sister. She moves in with him and Silver (Jessica Stroup) after the Shirazi family leaves the country, effectively turning her older bro into an ad hoc dad.

Will the newly cohabiting couple survive their unwanted third roommate? According to Michael, the workplace may offer up more issues. "Navid really tries to get closer to Silver. He hires her as his assistant and they both have their own offices in Shirazi studios, so it's a nice romantic thing in the house. It is very cool, but it also causes a lot of problems."
