The Bachelorette star Desiree Hartsock may want to keep suitor Brooks Forester away from her mom if he meets her family.   

Forester allegedly once cheated on a former girlfriend with a 51-year-old cougar named Tami Novick, Life & Style reported.

The magazine obtained photos of Forester posing and making out with Novick while vacationing in Puerto Rico in December 2011. Novick was reportedly unaware Forester was dating someone at the time.

"He apparently had a girlfriend," Novick's daughter, Joelle Krakower, told Life & Style.

"I was on vacation with my mom in Puerto Rico. That night, my mom went to a club and ran into Brooks and thought he was so cute! He was flirting with her from the get-go."

The following day, Forester reportedly walked up to Novick in the hotel lobby where they exchanged phone numbers.

"He told my mom he was 29, almost 30," Krakower explained of Forester, who was actually 26-years-old at the time.

The couple then allegedly met up that night for a fun little outing.

"Later that evening, they were dancing and drinking and making out for five hours," Krakower added. "My mom says he's a great kisser!"
