At least she's smiling through the heartache!

Britney Spears tweeted she was single yesterday after breaking up with boyfriend David Lucado, and the singer must have been looking to send another message by posting this Instagram, in which she confesses she wasn't feeling her best!

"If you ever have a really sh**ty day, find someone with shoes with hearts on them. Made my day," she says as she looks into the camera. The reason for her downtrodden mood? She allegedly split with her beau of eighteen months after reports surfaced that there was a video being shopped around of him cheating on her!

It's unlikely we will ever see the on-camera infidelity, though, because Brit Brit's father Jamie shelled out a "substantial" amount of money to purchase the rights to the video and prevent its release, TMZ reports.

Queen B will have suitors lined up in no time!
