Nelly is currently on tour with the country duo Florida Georgia Line . They are scheduled to play a show Saturday in Ridgefield, Washington. A rep for FGL did not respond to request for comment.

A police spokesperson said Nelly’s tour bus was parked near a Walmart at the time of the rapper’s arrest and that officers felt like they had probable cause for arrest, booking him into the SCORE jail in Des Moines, according to Q13 Fox.

Nelly had previously been arrested on several drug charges — including felony possession —while traveling in Tennessee in April 2015.

After a trooper claimed he smelled marijuana, police say they found a “small amount” of marijuana, drug paraphernalia and a plastic bag containing a substance they believed to be methamphetamine in his vehicle, according to a press release.

The rapper pled guilty to misdemeanor possession of marijuana and drug paraphernalia and was sentenced to a year of probation. After further testing, the substance in the bag was determined not to be methamphetamine and the felony charge against Nelly was dropped, according to the St. Louis Post-Dispatch.

In June, Nelly stopped by PEOPLE Now to promote his tour and spoke about how even though he was committed to his girlfriend Shantel Jackson, he wasn’t quite ready to tie the knot.

“The thing about marriage to me is…I take it very, very seriously. It’s something I’m only doing one time,” he said. “For me, it’s almost like society would prefer you to have been married and got divorced and tried it then to be married and stay married. For me, it’s more important to die married than to have been married and it didn’t work out. I want to leave this place knowing I was in love and somebody loved me and we were together, then to be like, ‘Well I’m never getting married again and I’m ruined.’ ”

Nelly continued, “If it happens, when it happens. That’s it! She’s locked in man, she’s trapped. Death do you part is serious around here!”
