If Elon Musk is your ex, sell his pics. Don't burn them.

If you are burning your ex's stuff soon after the breakup, then you are doing it all wrong. Elon Musk's ex-girlfriend, Jennifer Gwynne, just came up with an excellent idea to earn some money. Disclaimer, it only works only if your ex is Elon Musk. Maybe.

How Gwynne is making money off Musk: We once told you how complicated the world’s richest man’s love life is. Now, one of his college-time sweethearts is making headlines, as well as some money.

Jennifer Gwynne is now auctioning off photos and mementos from her once-upon-a-time relationship with the world's wealthiest man. She is using a Bonton-based RR Auction for the same.

Their love story: According to a CNN report, the Musk and Gwynne started dating in 1994 when they worked as resident advisers at a university dorm. After completing his graduation from the University of Pennsylvania, Musk decided to pursue a doctoral program at Stanford. He then dropped out to start his first startup, Zip2.

Musk and Gwynne were dating when he was at the University of Pennsylvania. She shared 18 candid photographs with him, along with several other mementos. She has shared photos of him going off in a dorm room, hanging out with his fellow resident advisers, and also cuddling with her.

What’s the status of her auction? Currently, a signed birthday card has earned the highest bid. The card reads, "Happy Birthday, Jennifer (AKA, Boo-Boo), Love, Elon.” Currently, the highest bid is for the card, at $10,000.

A gold necklace gifted by Musk is at number two. The CNN report mentions that the necklace contains an emerald from the Zambian mine that Musk’s father owned.

“When we went to visit Elon's mother in Toronto during the Christmas break of 1994, Elon gave me both the small 'love, love, love' note and the necklace. His mom had a number of these necklaces in a case in her bedroom, and Elon told me they were from his father's emerald mine in South Africa — he pulled one from the case. And because I had not gotten him anything as a Christmas gift (and I felt very guilty about that), he said we would consider the necklace an early birthday present for me,” Gwynne told RR, reports CNN.

"I wore the necklace for a number of years on and off, but it's mostly been in my jewellery box for the last 10 years (always reminding me of Elon, of course)."

The auction will end this Wednesday, September 14.

In her case, her ex’s stuff became profitable as no one knew back then that she was dating the to-be-richest man of the world.

Well, maybe it's a good idea to keep all the stuff from that bad relationship too. Who knows, someday they might earn you some money too!
