Kristen Bell says Spanx are the secret to her post-pregnancy figure.

The 'Veronica Mars' actress has revealed the slimming shapewear is what has kept her frame looking so slender since she welcomed her daughter Lincoln six months ago.

She explained: ''I get a lot of help from Spanx and there's a great compression garment called Design by Veronique, which has post-surgical compression garments. They're medical grade - they're like catsuits - and I wear them under outfits.''

Kristen is no rush to slim down after the birth, but is trying to shed a few extra pounds with a light exercise routine consisting of Pilates, running and cycling.

The 33-year-old blonde said: ''I have started running between 10 and 20 minutes, just on the treadmill three or four times or week, or two or three, depending on what the weeks look like.

''I just I started doing Pilates, I guess, probably three months ago to really get core strength back. I have a girlfriend who's a trainer and she comes to my house.

''Sometimes I go to SoulCycle, which is my worst nightmare, but I feel like Superman when I leave,I've never sweat so much in my life than when I've been there!''

Kristen admits she wants to return to her regular size but refuses to let the extra weight around her waist bother her like other women in Hollywood.

She added in an interview with E! News: ''It's like, by the way, don't you want to look like you've had a baby? I'm sitting here with you, I'm crunched over, I have a huge muffin top - who cares?!

''I'm definitely trying to lose it I want to be clear, but I'm not letting it keep me up at night and I am not letting it become the narrative of my life for the next year.''
