What do Fred Durst, Chris Kirkpatrick of 'N Sync, Carson Daly and Lady Gaga all have in common besides their careers in music? Getting dissed by Eminem, of course! Gaga is the most recent celebrity to fall victim to Eminem's sharp tongue, as he puts her on blast in a new Bad Meets Evil song called 'A Kiss.'

On the lewd and crude track -- which features looming chimes, ominous horns, and a hard-hitting hip-hop beat -- Eminem targets Lady Gaga by readdressing the transgender rumors that surrounded the 'Born This Way' singer at the start of her career. At the 3:10 mark, Eminem spits the line: "Tell Lady Gaga she can quit her job at the post office / She's still a male lady."

Despite Em's accusation of Gaga being a man, when the rumors began surfacing a couple of years back, the uber confident Gaga brushed them off like they were nothing; therefore, we doubt this will really bother the diva, especially considering Em's track record for hating on celebrities.

During 'A Kiss,' Eminem has some less-fighting words for 'Roman's Revenge' collaborator Nicki Minaj and Katy Perry, who he pretty much just calls a hottie. 'A Kiss' will be featured on the Bad Meets Evil -- which finds Em reuniting with rapper Royce da 5'9" -- EP 'Hell: The Seqeul,' due out on June 14.
