Blake Lively dieting for Christmas

New mom Blake Lively has set herself the goal of getting back into her old jeans by Christmas.

The former Gossip Girl star gave birth to her second daughter with husband Ryan Reynolds in September (16), and she's already determined to get back into shape, revealing that her early "New Years resolution" is to wear her favorite pants over the holidays.

"WILL fit into my jeans again gall darnet (sic),” Blake posted on Instagram on Monday (05Dec26), alongside a photo featuring yummy dishes mostly provided by food-delivery firm Epicured, adding, "This is not an ad. This is me getting it up for healthy food."

The post came three days after Blake took to Instagram on "#FitnessFriday" and posted a snap of herself hiding from a trainer at the gym. She added the caption: "Current mood".
