Now that Jennifer Aniston is in a sexy, new relationship with Justin Theroux, could the Just Go With It star have marriage on the mind?

Aniston and Theroux went public with their relationship Thursday night with a second date at Jen's favorite restaurant - The Tower Bar at Sunset Towers.

Even though it's obvious this isn't an engagement ring, we find it quite interesting that Ms. Aniston chose to wear her new bling on that particular finger while heading into the Universal Studios lot.

Jen and her new man hit up an MTV Movie Awards after-party, then continued the night at L.A.'s Soho House for some late-night lovin'. We're told the twosome couldn't keep their hands off each other all night. Love the mental visual!
