Ashley Olsen plays the older man field

Ashley Olsen, 21, seems to be sticking with older men these days.  Ashley has at least briefly hooked back up with Jared Leto, 36, who she dated for a short while in 2005.  The couple were noticed holding hands and kissing at the Art of Elysium gala in L.A. on Jan. 12, Us Weekly reports in its latest issue, on newsstands now.

“They looked like a couple and they were making out,” a witness tells Us.

But an Olsen rep says the duo are not back on:  They’re friends.”

Olsen was recently linked to older man, Lance Armstrong in November.
