Alex Pettyfer and Riley Keough have only been dating for about six months, so it's a bit shocking that she's already sporting an engagement ring.

Well, they say when you find the right person you just know. And if these shirtless pics of Pettyfer from the upcoming film Magic Mike are any indication, the fact that he's is ridiculously good looking made Keough's decision a little easier.

The couple have yet to confirm that they're tying the knot, but Lisa Marie Presley's little girl was spotted eating lunch at L.A.'s Le Petit Four with a hefty gem on her ring finger. Both have a history of dating within the entertainment world. Pettyfer's exes include Emma Roberts and Dianna Agron, and Keough's been linked to Ryan Cabrera and Jonah Hill.
