Brittany Mahomes just gave her followers a deeper look into her Sports Illustrated Swimsuit photoshoot with some behind-the-scenes pics ... and check 'em out, they're steeeaaaaamy!!
Patrick's wife posted the shots on her Instagram page late Monday night -- in a clear attempt to hype up this week's release of SI's annual bikini edition.
In one image, Britt can be seen rockin' a cowboy hat while in a barely-there red two-piece.
