R&B star Ciara was forced to perform at a recent in-store signing with mustard oozing out of her shoes after rapper Yung Joc played a practical joke on her.
The pair has been touring together on the Screamfest '07 tour and prankster Yung Joc - real name Jasiel Robinson - has been catching the Goodies singer out with pranks at every stop.
And he insists his mustard gag is the best to date. Yung Joc explains, "Me and T-Pain put mustard packets in her shoes.
She was doing, like, a live in-store in with the kids and this little girl said, 'Ciara, you've got some yellow stuff coming outside of your shoes.'"
