Jessie James Decker's got us all green with envy ... envy over NOT being on Miami beach to see this shoot going down live.
Jessie's frolicking in a green bikini and flauntin' what her mama gave her while shooting a commercial. Unclear what product she's pimping but it's gonna be hard to upstage Jessie's bikini bod ... which is en fuego!!!
Speaking of what mamas gave ... Jessie and her ex-NFL hubby, Eric Decker, just had baby #3 -- a little boy -- back in March. Snapback mode, in full effect!
