Reese Witherspoon celebrates 41st birthday with her look-alike kids

/ Source: TODAY

Reese Witherspoon turned 41 Wednesday and the "Big Little Lies" star marked the occasion with a birthday bash. While she was the guest of honor at the event, there were a couple of other special — and familiar-looking — attendees.

In fact, one party pic might just have you doing a double take. Or even a triple take.

The actress is front and center in the Instagram shot, flanked by two look-alikes — 17-year-old daughter Ava and 13-year-old son Deacon.

"There’s nothing better than celebrating my birthday with my wonderful kids!" Witherspoon wrote in the caption, adding the apt hashtag #ProudMom.

Witherspoon's youngest child, 4-year-old son Tennessee, didn't make it into the family photo but an Instagram shot she shared earlier in the week shows that he's another perfect match for mom — and his big brother and sister.

The birthday girl posted other pics from the big day, including a snap of her modeling a festive dress made by her own label, Draper James.

She also added a photo of her rose-and-berry-covered birthday cake.

Ava got in on the social media sharing too, offering her followers a look at the moment mom made a wish.

"Happy birthday to one of my best friends," the teen wrote.
