There are clearly no hard feelings between TV presenter Caroline Flack and One Direction's Harry Styles.
After news broke of the boy band's history-making US number one with their debut album, the 32-year-old tweeted her congratulations.
"Incredible news for One D!!!! HUGE news x," wrote the presenter, who split amicably with 18-year-old Harry earlier this year.
And she wasn't the only famous face to flag up the boys' achievement.
X Factor boss Simon Cowell, wrote: "I couldn’t be happier for @onedirection, it is an incredible achievement. They deserve it. They have the best fans in the world."
Runner-up on the talent show Olly Murs tweeted: "WELL DONEEEEE!! @onedirection #1 with Debut Album in US Billboard Charts!! 1st Ever Uk Band to do it!! That's amazing stuff lads!! Ledge!!"
