Bre Tiesi's killing 2 birds with one stone -- hitting the beach to show off her expensive new wedding ring ... and flaunt her bangin' bod once again.
Johnny Manziel's wife soaked up the sun in Miami Wednesday afternoon in a tiny bikini ... which has kind of become her thing. Johnny was nowhere to be seen, so it's possible he's back to practicing for a hopeful return to the NFL.
TMZ Sports broke the story ... Johnny and Bre tied the knot last week in a private ceremony in California. The couple got engaged last March.
Bre's clearly cool with keeping the honeymoon vacay going without him.
