Salute the onesie! Leigh-Anne Pinnock and the rest of the gals from Little Mix had a lot to celebrate last night — it's their three-year anniversary together as a group! So naturally, they went on a total Instagram spree, posting silly pics and videos of their enormous celebration. Side note: Where can we pick up a onesie as cool as Leigh-Anne's and join the party??? (Just sayin'.)
