Jessica Simpson's daughter Maxwell has inherited her mom's sense of adventure! The adorable 2-year-old tot took a New Year's dip in the ocean over the weekend — with all her clothes still on!

Simpson shared the super-cute snap via Instagram late on Sunday, Jan. 4, with the caption, "A January Swim #FEARLESS." The photo was taken during a weekend family trip to the beach, other photos of which she shared with fans on Saturday.

In the pic, Simpson's mini-me is wearing jeans and a striped sweater, her pretty blonde hair flowing in the wind on what appears to be a mild but breezy January day.

But despite her legs being submerged in the ocean, happy Maxwell is sporting a huge, open-mouthed grin as she wades through the waves still wearing all her clothes!

Simpson, husband Eric Johnson, and children Maxwell and Ace, 18 months, have spent the festive season enjoying some quiet family time away from social media. But having shared her cute family beach outing snaps this weekend, it looks like proud mom Simpson is ready to return to spotlight in 2015. Keep the photos coming, Jess!
