OJ Simpson to marry pen pal?

OJ Simpson has reportedly proposed to a woman that he exchanges letters with while in jail.

According to The Globe, the former football player fell for the "young blonde" called Anna despite never meeting her in person.

"They've been writing to each other for a while now," a source said.

"She sent him her photo, and he just flipped for her."

The 62-year-old will allegedly marry his pen pal while still behind bars in a Nevada prison for a 2008 armed robbery charge.

The marriage would be Simpson's third.
