Blake Lively looked amazing during her interview on “The Tonight Show with Jay Leno”. This is definitely the body of a girl who works out and watches what she eats.

She admitted during the interview she tried to sabotage Ryan Reynolds dieting efforts during the filming of ‘Green Lantern’ with cupcakes! ”It was just a way to sabotage Ryan. He was working out as much as he was, and I’m the girl. I’m supposed to look better.”

Blake Lively was photographed in Saint Paul de Vence, France recently. Blake always seems to be in amazing shape! Here’s an article about Blake’s diet and exercise regime

Blake Lively — who flashed her gams in a Marchesa mini at Monday’s Met Gala — has been hitting the gym with star trainer Bobby Strom to shape up for Green Lantern (which costars Ryan Reynolds).

“She always looks good,” Strom told Us of the Gossip Girl star, 22. “But she has to do stunts, so we’re focusing on core and strength training.”

Her workout routine includes four-day-a-week, 90-minute circuit training sessions full of planks, pushups and walking lunges in a gym near the film’s (out June 2011) New Orleans set.

“She looked at her stomach and said, ‘I have abs!’” Strom tells Us.

Her diet? Oatmeal with a handful of blueberries, salads with chicken and balsamic vinaigrette for lunch and fish and veggies for dinner. (Lively also blends fruits and veggies with a juicer, and avoids noshing on too much dessert by eating just a “fork-full.”)

Her food splurge: The 5-foot-10 actress loves to cook and eat Greek food.

“You would not believe what she could consume,” Strom says. “The Greek fest that she made… crepes with cream cheese in them… we could only eat half of it. She ate all of hers and then went back and ate somebody else’s half.”

Thats what I’d say to Blake Lively after camping outside her house for a few days. Deranged fan? …Perhaps…

Here’s how it would go down..

Blake Lively: Hi there, how are you? It’s always so good to meet fans
Me: Blakey you are fit
Blakey Lively: Blakey?? Is that a joke…I don’t even know you and now you’re giving me these creepy nicknames!
Me: B-b-blakey..you are fit..
Blake Lively: Oh…I see..*pages security*

[Security zap me with a tazer gun]

Me: WHY BLAKEYYYYY WHYYYY! All I wanted to do was bask in the glory of your fitness!

Then she’d realize it was all a big misunderstanding and probably would give me some money.

Anyway here she is at the premiere of Sisterhood of the Travelling Pants 2

The lovely  Blake Lively is still looking as thin and fit as ever. Here are some recent candids of her filming Gossip Girl season 2.
