If you don’t know Bonnie McKee, it’s probably because you’re not famous. Because, seriously, it seems like she knows everyone who’s anyone in Hollywood.

In fact, she knows them all so well, she was able to get them to appear in the video for her recent release ‘American Girl' -- which we can pretty much guarantee will be stuck in your head 'Call Me Maybe'-style for the rest of the summer.

It helps that McKee is a songwriter, and a successful one at that, so she’s worked with a lot of these people before. This is the woman who gave us Taio Cruz’ ‘Dynamite,’ Katy Perry’s ‘California Gurls’ and ‘Teenage Dream,’ and Britney Spears’ ‘Hold It Against Me’ -- among many other pop hits that tend to take up residency on the looping playlist in your brain.

So maybe it's not surprising that Perry, Adam Lambert, Macklemore, Jason Derulo, Tommy Lee, everyone from ‘Fashion Police,’ KISS, Kathy Griffin, George Takei and a ton more stars were all willing to play along and be in her vid.

Check out the clip above and see if you can spot them all (bonus points if you can pick out Tommy Lee).
