On this week's 90210, Donna Martin returned, chock full of news:

Her and David were separated.

Many former Beverly Hills, 90210 fans - including the author of this post! - were peeved over the storyline. It seems like a low blow to followers of that show, considering how the finale was based around Donna and David's wedding.

But Tori Spelling is defending the development to TV Guide.

"It was something we discussed, the producers and I, and I thought it was real," Spelling said. "There's just a real storyline there. What happens when a couple of high school sweethearts grow up and become adults, and parents, and have different career paths? Sometimes you kind of move away from each other."

The actress is also quick to note separated doesn't necessarily lead to divorce.

"We'll see what happens," said Spelling. "I know the audience loves David and Donna together and hopefully it will all work out."

What do you think of the Donna/David split? Is it a cheap, unfair plot device? Or a logical continuation of this relationship?
