Jimmy Kimmel just made a ton of people's dreams come true last night. For his #MashUpMonday series, he nabbed Warren G and the inimitable Kenny G to perform "Regulate." This is the fourth and final installment of "Mash Up Mondays," which featured "Weezer and ZZ Top," "Morris Day and the Haim" and "Aloe Blaccstreet."

Warren G is heading out on a week-long tour next month to celebrate the 20th anniversary of the song and reissued the album, Regulate… G Funk Era, last year, as well. R.I.P. Nate Dogg.
