Perhaps the more rock 'n' roll thing would be, is to pretend he doesn't even know who Rihanna is.

But outspoken Gene Simmons has decided to ridicule her instead, branding the popstar as 'fake'.

During a Kiss press conference yesterday, promoting the band's new tour with Motley Crue, the frontman claimed that only is the Rude Boy star 'bulls***', but everyone else whose name ends with A.

He said: 'We’re sick and tired of girls getting up there with dancers and karaoke tapes in back of them. No fake bulls***.

'Leave that to the Rihanna, Shmianna and anyone who ends their name with an A.'

Backstage, drummer Tommy Lee agreed with Simmons, branding her 'karaoke' style as 'pathetic'.

He told Billboard: 'No disrespect to Rihanna, she’s a great singer, but we’re in a slump for some s*** that has some personality and appeal beyond a bunch of pop stuff that’s floating around out there.

'I’m glad he said that actually, because I don’t think I can bear watching another f***ing award show that is just a little bit better than American Idol.

'It’s f***ing pathetic to watch people go out and f***ing karaoke with a bunch of lights and video.

'It’s all completely watered down.'

However, in contrast to the tirades, Gene rather politely thanked George Lopez for the press event held in Hollywood.

He tweeted: 'Thank you @georgelopez for intro-ing the KISS Motley Crue Tour PR Event.'

Simmons revealed the two groups will tour across the US this summer, both playing 90-minute sets.

Alongside their 40-date venture, Kiss will cross the Atlantic in July to headline UK festival Sonisphere.

Last December, Gene embarked on another feud, this time with the Queen of Pop.

He told TMZ that he was unhappy with Madonna performing at the Super Bowl 2012 Halftime Show.

Implying she can't sing live, he ranted: 'I love all karaoke singers, I love all the girl singers who get up and sing with tapes... shame on you! By the way, Madonna's terrific... I hate the tapes.'
