After seeing the commercial for ABC's new guilty pleasure drama Mistresses about 8,000 times yesterday, I got this Selena Gomez song completely stuck in my head. So I thought, oh hell, if this ain't a Wicked Guilty Pleasures post I don't know what is. Guilty Pleasure tunes and TV. Perfect! And then Tony went and posted Selena Gomez playing her bestie's song I Knew You Were Trouble today at Totally Covered...I was going to scrap this post, but then I thought, awww heck let's make it Selena Gomez Day at the blogs.
