Bonnie McKee, the singer-songwriter responsible for writing your fave's best songs, is giving the whole solo pop star thing another go.

The pink-haired penner-turned-pop princess has scribed some of the most major pop radio bangers of the past decade, including Katy Perry's "Teenage Dream," "Part Of Me" and "Wide Awake," Taio Cruz's "Dynamite," Kesha's "C'mon," and Britney's "Hold It Against Me." (And in case you'd like to see her sing all of those songs at once, watch her still impressive smash medley.)

But, the thing is, Bonnie isn't satisfied simply sitting back and watching other stars hog the spotlight. And so, after sipping on Slurpies in the 7-11 parking lot two years ago with "American Girl" and discoing down with zombies on "Sleepwalker," the accomplished Top 40 pop writer has returned with "Bombastic," the lead single and title track from her forthcoming EP, due out June 30.

And, uh...no more Ms. Nice Guy.

"You know I'm bringing bombastic / I'm feeling fucking fantastic!" Bonnie gleefully roars across the guitar-heavy blast of a massive chorus, serving "American Woman"-meets-Avril Lavigne for a massively over-the-top burst of shout-y pop energy. A song about determination to the point of becoming ever-so-slightly deranged? A perfect fit for Bon Bon! (As with Brit's legendary Britney anthem "Bombastic Love," the jury's out on whether or not Bonnie 'gets' that the definition of "bombastic" is "pretentious" or "high-sounding but with little meaning." She's likely just being ironic, as Madonna would say.)

And then, there's the video. And, oh, the video.

With a song as raucous as "Bombastic," Bonnie had no choice to break out the big guns — err, buns for the accompanying visual. The result? A super silly, super porn-y take on an '80s workout video gone mad (Bonnie McKee's Bombastic Workout!), clearly inspired by Heidi Montag's ahead-of-its-time "Overdosin'" — but mostly, it is an explosion of butts. SO MUCH BUTT. Other body parts too. But mostly butt, "Anaconda" style. She does have a nice, uh, asset, so why not show it off in some very generous leotards?

Side note: Bless you, Bonnie, for this '80s retro moment bringing to mind the still-iconic workout portion in the parody of Brenda Dickson's Welcome To My Home. "I'm now hermetically sealed to the bike!"
