Little Mix celebrate their 4th No.1

It's their fourth chart-topper

Little Mix just scored their fourth number one hit with 'Shout Out To My Ex' and joined a special elite in the process.

They're now only the third artist to enter the charts at the highest position following Major Lazer and Justin Bieber's 'Cold Water' and Zayn's 'Pillowtalk' (awkward).

'Shout Out To My Ex' has also enjoyed the biggest opening week download sales for a No.1 single this year and shifted 95,000 combines sales.

"We want to say a massive thank you for getting us here," Little Mix said. "Everyone can relate to this song. Everyone's had an ex or a bad relationship and this is a big positive break up anthem."

Elsewhere last week's chart topper James Arthur slips to two with 'Say You Won't Let Go' while Chainsmokers and Halsey's 'Closer' is also down a place to three.

The Weeknd and Daft Punk's collaboration 'Starboy' is at four while singer and actress Hailee Steinfeld scores her first UK Top 10 with her Grey and Zedd collaboration 'Starving', which climbs 12 places to five.

Maroon 5 enter at 16 with their Kendrick Lamar collaboration 'Don't Wanna Know', giving them their 18th UK Top 40 single in the process while Fifth Harmony's 'That's My Girl' enters at 31.

Finally, Galantis & Hook N Sling are up seven places to 37 as Shawn Mendes's latest single 'Mercy' climbs the charts by two places to enter the Top 5.
