Hollywood beauty Jennifer Garner has lined up a raunchy movie comeback straight after giving birth to her baby with husband BEN AFFLECK - in a new erotic thriller.

The ELEKTRA star will deliver the couple's first child early next month - but will be heading straight to the gym to get in shape for her role in SABBATICAL.

Garner will play a bored wife who suggests she and her husband spice up their lives by having affairs.
