She only gave birth to son Noah two months ago, but Megan Fox has wasted no time in snapping back into shape.

And after dressing down in jumpers and leggings over the past few weeks, the stunning actress has finally decided to show off her post-baby body in all its slender glory.

The 26-year-old star opted for a fitted but ladylike mint green dress as she promoted her latest movie This Is 40 at a photocall in Los Angeles on Wednesday.

Looking mint! Megan Fox chose a stunning light green dress to show off her post-baby body at a photocall for her new movie This Is 40 in Los Angeles on Wednesday

Dressed to impress: Megan, 26, teamed the pretty outfit with a pair of sky-high nude heels

The pretty dress clung to Megan's figure in all the right places, with the origami-style pleats proving an on-trend addition to the outfit.

As she was: Megan looked blooming ahead of son Noah's birth in early September

Megan, who is married to former 90210 star Brian Austin Green, teamed the dress with a pair of sky-high nude heels as she posed up for photographers at the event.

Megan and Brian welcomed baby son Noah Shannon - their first child together - into the world on September 27.

Announcing the birth on Facebook, Megan admitted she and Brian were grateful for having a 'peaceful few weeks' with their son before telling the world of his arrival.

She wrote: 'We have been very lucky to have had a peaceful few weeks at home, but I would like to release this myself before others do.

'I gave birth to our son Noah Shannon Green on September 27th. He is healthy, happy, and perfect.

'We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love.

'Thanks to those of you who wish to send your positive energy and well wishes.

'May God bless you and your families abundantly.'

While Noah is Megan's first child, Brian has a 10-year-old son Kassius from a previous relationship.

This Is 40 is Judd Apatow spin-off from his highly-acclaimed comedy movie Knocked Up.

The film takes 'A look at the lives of Pete [Paul Rudd] and Debbie [Leslie Mann] a few years after the events of Knocked Up,' according to the official description on IMDb.

And as the couple tries to cope with the trials of raising a family and getting a little too comfortable in their long-term relationship, the storyline unfolds.

Hot mama: Megan certainly knows how to draw attention to her favourite assets

It looks like she's having those atrocious tattoos removed. Time to grow up, lass!

Haven't had much respect for her the last few years. Now that she seems to have turned her life around, marriage, children and removing her stupid tatoos her stock is way up with me again. - eramthgin, housotn, 30/11/2012 17:32 ---- Sorry for being harsh, but these are exactly the reasons why people completely forgot her : she wants to appear like a politically correct cartoon character now, and she's not interesting anymore.

I liked her when she used to tell funny jokes in interviews with men¿s mags, but now she¿s really just a boring robot with a ¿transformed¿ face, she can be liked only by 50 year old housewives, and looking at the comments here, even male readers are mocking her (I'm a man too). Sorry, career over, only cameos and TV commercials.

She's looking radiant- but I just don't get how these women can just bounce back into shape right after their pregnancies!
