Katy Perry and John Mayer partied at Las Vegas strip club Spearmind Rhino over the weekend.
The couple - who split briefly before reuniting earlier this month - were spotted in the city with friends on Sunday (10.09.12) where it was revealed they had enjoyed a night out at the Notorious Spearmint Rhino strip club.
A source told People magazine ''They were together in a group. As for whether they got dances, they were in a strip club ... you do the math.
''The group had so much fun, they stayed until 5 a.m.''
Earlier, they were spotted checking into the Wynn Hotel together.
Katy, 27, was thought to have been left heartbroken when John - who has dated a string of Hollywood beauties, including Jennifer Aniston, Jessica Simpson, Taylor Swift and Cameron Diaz - ended their brief fling at the end of August.
A source said at the time: ''She is making it seem like it wasn't serious with John, but she is hurt.''
Another friend said the 'Teenage Dream' singer - who announced she was to divorce comedian Russell Brand after 14 months of marriage at the end of 2011 - was ready to get serious with John, who she reunited with earlier this month.
They said: ''She doesn't want to get her heart broken again, but she feels a real connection and wants to see where things go.''
Since splitting with Russell Katy also briefly dated Florence + the Machine rocker Robert Ackroyd in the spring.
