Natalie Portman's fitness regime revealed!

The starlet’s been getting her post-baby body back in shape with the help of fiancée Benjamin Millipied

She gave birth to first child Aleph just four months ago, but it seems already Oscar-winner Natalie Portman has begun to whip her post-baby body back into shape.

And who better to help than fiancé Benjamin Millipied?

The Black Swan beauty roped her ballet dancing hubby-to-be into a jog around LA yesterday, and the pair hit the pavements to make most of the sun.

Already sporting a super-slim frame, the starlet has shed her baby weight in no time at all, and looked better than ever as she enjoyed some exercise.

Natalie gave birth to adorably baby Aleph back in June, and has since been spied on several outings with the tiny tot.

Earlier this week the family took a trip to the library, before visiting California's San Marino Botanical Gardens.

But it’s unlikely we’ll be seeing much more the super-cute tot any time soon.

Earlier this year the starlet revealed she’s planning on keeping a low profile with her little one, to enjoy family life at home.
