Riley Keough and Alex Pettyfer Engaged?!?!?

Wowza!
This past weekend we reported on the passion burning in Alex Pettyfer and Riley Keough loins.
Well, it seems the burning has spread to the heart because, apparently, the two are engaged!!
A sparkling green rock was spotted on Elvis’ granddaughter’s ring finger on Monday, while the cute-as-buttons couple noshed on some lunch at Le Petit Four in LA.
If the rumors are true, it means the couple are getting serious after only 6 months of dating.
Plus, Riley is only 22, and Alex is a baby at 21!!
We hope it’s a very long engagement. Enjoy your youth guys! There’s plenty of time to get serious later on!!
We don’t want anyone to be crying in the chapel!! (we couldn’t resist ONE Elvis pun…)
The Magic Mike star has also been linked to Dianna Agron and Emma Roberts…are his dating days really over??
What do U think about the young couple’s commitment?
