50 Cent is now $78 million richer as he has locked down a hefty endorsement deal with Frigo Revolution Wear to promote a brand of upmarket men's underwear.

Making the announcement via his Instagram account on Monday (Dec. 15), Fif boasted, "I just did a deal for $78 million for underwear. What did you m*********s do today?"

Later that day, in true Fiddy fashion, he posted another snap of himself in his lavish kitchen with some bundles of cash resting in between two slices of bread — with some on the side, of course — before appearing on Late Night With Seth Meyers to promote the briefs, which retail for $100 a pair.

When speaking with Meyers, the "21 Questions" emcee also promoted his upcoming film with Melissa McCarthy, spoke on working with retired Yankees icon Derek Jeter and even explained why he is accepting Bitcoin payments for his most recent album, Animal Ambition, saying, "All money is money."

This sizable endorsement isn't a surprise as, according to Forbes, 50 Cent has accumulated a fortune of more than $140 million throughout his career, ranking him No. 5 on the list of hip hop's wealthiest artists.
