Sunday proved to be a very special day for The Saturdays. Not only did the ecstatic girls bag their first ever number one single when What About Us went straight to the top of the charts, but their hit track also became the fastest-selling single of the year.
Immediately upon hearing the news, Rochelle Humes, Una Healy, Mollie King, Frankie Sandford and Vanessa White, took to Twitter to share their delight and thank their fans.
"Omg. You guys have made this all possible. I cannot believe that are the official number 1. For once I'm speechless. We did it guys," expectant Rochelle tweeted, while Mollie added, "Team Sats I cannot thank you enough! You have made my dreams come true! That little 6yr old inside me has come out, I'm so emotional!"
Mum-of-one Una took the opportunity to pose with the groups' number one trophy and share the photo with her followers, and Vanessa wrote, "Thank you sooo much to everyone who bought #WhatAboutUs - we are so happy :) WE DID IT!"
Topping the charts was the perfect swan song for pregnant Rochelle, who gave her last performance with The Saturdays before the arrival of her first baby. The singer, 24, dazzled in a silver sequined dress as she took to the stage with the girls at G-A-Y on Saturday night.
Rochelle, who also celebrated her birthday on Thursday, received a cake, teddy bear and a bouquet as she took a final bow before heading off on maternity leave. "The best send off ever! Thanks G.A.Y…sad that it's my last show for a while but I don't wanna give birth on stage. Lol. Love you all xxx," she tweeted afterwards.
The Saturdays have seen their popularity skyrocket since their reality show, Chasing The Saturdays, first aired in the US. But unfortunately, with that success, has also come some negative attention.
The girls recently admitted they do get upset by hurtful comments made by 'Twitter trolls', saying that online bullying has been so bad in the past that they had to call the police.
"I'd be lying if I said they didn't upset you," Vanessa told More magazine. "(One tweet read), 'Hope your plane crashes and you all die'."
Una, who has a one-year-old daughter Aoife Belle with husband Ben Foden, added, "You may only see one tweet, but it can get you down for the whole day. At one point I had the worst abuse for going out drinking. Whenever I blocked (the troll), they'd reappear under a new name.
"It got so bad I called the police. They said, 'Well, actually, that's not our department'. There should be stricter laws to stop the faceless cowards."
