Britney Spears has opened up about her ''sh***y day'' following her split from David Lucado.

The 32-year-old pop star, who is thought to have dumped her boyfriend yesterday (28.08.14) after a video emerged of him allegedly cheating on her, alluded to her romantic woes in a new inspirational video posted to her Instagram account.

The 'Piece of Me' hitmaker captioned the short clip: ''When you're having a shitty day... (sic)''

In the video, she said: ''If you ever have a really, really shitty day, find someone with shoes with hearts on them.''

After pointing the camera to a pal whose shoes are adorned in red hearts, Britney added: ''Made my day!''

The singer confirmed the end of her 18-month relationship on Thursday when she wrote on Twitter: ''Ahhhh the single life! (sic)''

The split comes as footage is being shopping around of David reportedly dancing with and kissing a mysterious woman.

But it seems her former boyfriend is hoping to patch things up with Britney.

A source said: ''David is very, very in love with Britney. This is unfortunate and he hopes that it all works out.''

Britney and David first got together in March 2013 just a couple of months after she called off her engagement to Jason Trawick.
