It's about time, Kate Upton!

Fashion's darling du jour finally caught up with the rest of the world and joined Instagram last week.

Naturally, being the media savvy gal that she is, the 21-year-old model announced the creation of her official account via Twitter:

So what does a Sports Illustrated Swimsuit cover girl share with her Instagram fans? Sexy bikini photos, obvi.

The Vogue rising star posted her now famous zero gravity photo from the 2014 Sports Illustrated Swimsuit issue and shared a sexy snap of her and fellow SI cover star Chrssy Teigen, who didn't look so bad herself in a white bralette.

Keep those photos comin', Kate!
