Hugh Hefner would be proud.

Mick Jagger was seen out and about in Paris last week with his new girlfriend, 23-year-old Noor Alfallah. Large age gaps are nothing new in Hollywood, but this 51-year difference -- Jagger is 74 -- will certainly raise some eyebrows! (Hefner, who passed away in September, and wife Crystal Harris were 60 years apart.)

Jagger and Alfallah, who reportedly has completed a UCLA grad school program, have been dating for about a month, Us Weekly reports.

The two met through mutual friend Brett Ratner, who made major headlines on Wednesday as six women came forward to publicly accuse him of sexual harassment and misconduct. Alfallah referred to him on Facebook as her "best friend and mentor."

Alfallah and her family certainly appear to be well-connected in the Hollywood community as sister Remi Alfallah reportedly dated Michael Jackson's son Prince a few years ago.

Jagger recently became a dad for the eighth time when ex-girlfriend Melanie Hamrick gave birth in 2016. Most of his children are in their 30s and 40s. He was in a long-term relationship with fashion designer L’Wren Scott from 2001 to 2014, when she committed suicide.
