Vince Neil has reportedly called it quits with longtime partner Rain Hannah. According to a new report from TMZ, the Mötley Crüe frontman ended the relationship after discovering, through one of his assistants, that Hannah was allegedly involved in an affair.

A source told the outlet the infidelity was somewhat of an “open secret” among Neil’s close associates, though no one dared to tell him. That changed when one of his assistants, apparently frustrated by the ongoing situation, stepped in to inform Neil that his girlfriend of 15 years was allegedly being unfaithful.

The news of the breakup comes just a few months after Hannah survived a devastating private plane crash that tragically killed the pilot. Although the aircraft belonged to Neil, he was not on board at the time. Hannah sustained serious injuries in the incident, including five broken ribs.

Meanwhile, Mötley Crüe recently had to push back their highly anticipated Las Vegas residency. The delay was attributed to Neil undergoing a still-undisclosed “medical procedure.” The rescheduled shows are now set to take place at Dolby Live at Park MGM on September 12th, 13th, 17th, 19th, 20th, 24th, 26th, 27th, and October 1st and 3rd.

Looking ahead, fans can also catch the band this fall at the “Rock the Tides” destination festival, taking place November 7-9 along Mexico’s Riviera Maya. Mötley Crüe will co-headline the event with Def Leppard, with support from Bret Michaels, Extreme, Buckcherry, Living Colour, and more.
