The pilot of the Lollipop star's private jet was forced to make an emergency landing in Nebraska on Monday (13Jun16), so Wayne could get medical treatment on the ground.

Reports suggest the rapper refused medical attention and then suffered a second seizure as his plane took off again.

Now, his rep tells TMZ the rap star's latest health scare came after he ran out of prescribed medication and couldn't find a replacement in Wisconsin, where he was flying from when the seizure drama occurred.

A source close to Wayne tells the website the rapper's private jet was forced to make two emergency landings because he hadn't been taking his medication and had several epileptic attacks on the plane.

Wayne's rep tells TMZ a pharmacy he visited in Milwaukee, where he was performing, didn't have the medicine he needed in stock.

Lil Wayne put his seizure drama behind him to perform at the E3 Expo in Los Angeles on Wednesday (15Jun16). The 33-year-old had been due to perform at the Samsung booth at the annual video game conference on Tuesday (14Jun16) to promote his skateboarding game Sqvad Up but he was in the hospital at the time.

He is also scheduled to hit the stage at the Sprint Center in Missouri on Saturday (18Jun16).
