The newlywed singer couldn't contain her excitement at seeing the comeback single top the singles chart on its first week of release.
A jubilant Cheryl said: "WE DID IT! No. 1! You guys are incredible. Thank you so much for your loyalty, love and support. I love you like crazy."
It tops a pretty a-mazing month for Cheryl who (as we all know!) married boyfriend Jean-Bernard Fernandez-Versini in a secret Caribbean ceremony on 7 July.
They had been dating for a few months before their Mustique nuptials, which were kept so secret, no one even knew they were engaged.
Crazy, stupid love indeed!
This marks Cheryl's fourth solo number one in the UK charts following the success of past tracks 'Fight For This Love', 'Promise This' and 'Call My Name'.
