Notre Dame freshman wide receiver Justin Brent might be in a bit of hot water with the university after not heeding to preseason warnings about the danger of social media.

Notre Dame Freshman Receiver Justin Brent Shares Photo in Bed with Adult Film Star Lisa Ann

Brent made headlines last week when he was photographed on a public date with 42-year-old adult film star Lisa Ann. The photo of the date was followed by a photo of the pair in bed together, visibly topless. TMZ reports that Notre Dame warns its athletes about taking caution to what is shared on social media.

"We spoke to a rep for the school who wouldn't comment specifically about Brent -- but said in general, 'We tell our players, understand when you're at Notre Dame the attention is great. You have to be smart off the field. Especially with social media,'" the report stated.

Notre Dame Freshman Receiver Justin Brent Reportedly Dating Adult Film Star Lisa Ann

Notre Dame had a bye last week, but it's still shocking for a college freshman to be seen out on the town with an adult film star in New York City on a weekday, no less. Brent was a long way from South Bend, Ind., but the 6-foot-2, 205-pound receiver has yet to see action on the field this year so it's possible he wasn't missed in practice.

Ann is best known for impersonating 2008 Republican Vice Presidential candidate Sarah Palin in parody movies. She has worked in the adult film industry since 1993, but took a hiatus in 1997 before returning in 2006. She is a member of multiple adult film halls of fame. She took to Twitter to address the reports last week:

Ann is a well-known sports fan, and hosts a Monday night radio show called "Lisa Ann Does Fantasy" with co-host Adam Ronis on Sirius/XM Fantasy Sports Radio.
