Jennifer Garner to quit 'Alias'?

The next season of Alias may be Jennifer Garner's last, according to a report on The Insider.

A source told the programme that the actress had "made it clear that she probably won't be returning to the show next year for a sixth season."

Garner recently married actor Ben Affleck and is expecting their first child. The pregnancy will be written into the cult show's fifth season, which airs in the US from September.

Rachel Nichols, who joins Alias as a new spy being trained by Garner's character, is being tipped to take the lead role if Garner quits.
