The 28 year-old American model was at Michelle Obama's 50th birthday bash with her husband John Legend. When Beyonce's set started, Teigen got a little excited - who can blame her? We're talking booty shaking like you've never seen, the kind that - when teamed with the best bubbly in the White House - leaves serious bruises.
Check out this Instagram photo that Chrissy posted with the caption: "Tell me this isn't the worst bruise you've seen. #dancingtobeyonce"
Chrissy, you're a girl after our own hearts and the war wounds (that bruise is mega!) clearly mean you were owning it on the dance floor.
Beyonce wasn't the one performing on the night either, according to TMZ John Legend also worked his magic for the fabulous FLOTUS.
If you love Bey like we do, you'll love this gallery all about she who "run this motha"...
