Then & Now: What Our #CapitalSTB Stars Looked Like When They First Became Famous

1. Ariana Grande

There are ACTUALLY 7 years between these two photos. Between her appearing at a movie premiere in 2009 and arriving at the BBMAs earlier this year, Ari has definitely stumbled upon the fountain of youth, we're sure of it! (Pics: PA Photos)

2. Tinie Tempah

Tinie dropped his debut single, 'Pass Out', back in 2010 and we couldn't NOT have him belt it out at the Ball that year. Fast-forward 6 years and he's back again looking as dapper as ever, but with an even stronger facial hair game. (Pics: PA Photos)

3. Little Mix

Perrie, Jesy, Leigh Anne and Jade became Little Mix on The X Factor back in 2011, and they've ALWAYS looked fierce on the red carpet. While the girls have all grown up and gone through SO much, they're stronger than ever in 2016 and we can't wait to see what style they'll be rocking at this year's STB. (Pics: PA Photos)

4. Nathan Sykes

Nathan first captured our hearts back in 2010 as part of The Wanted, and just 6 years later he's grown up to become an international superstar. Even though more than half a decade's passed, that cheeky smile is still the same. (Pics: PA Photos)

5. Nick Jonas

Talk about a transformation! The squeaky-clean Jonas Brother looks NOTHING like the hunky 'Close' singer on the right. 8 years have whizzed by since the first photo was taken, and Nick's transformed his image by ditching the floppy hair and growing out a cheeky bit of stubble. (Pics: PA Photos)

6. Craig David

A fresh-faced and jumper-clad Craig David picked up 3 MOBOs back in the year 2000 for his debut album 'Born To Do It'. 16 years later he's making his #CapitalSTB debut - and we're predicting a much suaver look on the red carpet. (Pics: PA Photos)

7. Jess Glynne

While Jess hasn't been around as long as some of our other Summertime Ball-ers, she's truly transformed as an artist since 2014's 'Rather Be'. Jess has been fearless experimenting with her fashion, makeup and hairstyles in the last 2 years, so we can't wait to see how she'll wow us at Wembley this weekend! (Pics: PA Photos)

8. Will.i.am

It was TWELVE years ago that Will and the rest of the Black Eyed Peas dominated the chart with 'Where Is The Love' - and in that time he's been a busy man. From charities to technology, television shows to making the odd bit of music, Will's been doing it ALL since 2004! (Pics: PA Photos)

9. Mike Posner

'Cooler Than Me' was one of the hottest tracks of summer 2011, so we just HAD to get Mike Posner over to perform it live at our Ball. 5 years later 'Ibiza' is keeping those summer vibes going, so a very blonde Mike is coming back to Wembley. (Pics: PA Photos)

10. The Vamps

LOOK HOW YOUNG THEY LOOK! Brad, Tris and James look positively adorable on their first ever promo pic from 2012. Four years later they've (sorta) grown up, and even gained a Connor. Brad's hair STILL looks the same though - how does he do it? (Pics: PA Photos)

11. Flo Rida

If this was a game of Spot-The-Difference we'd have to just give up. The photo on the left was Flo performing his debut single. 'Low', on MTV's TRL (remember that?) back in 2008. The one on the right was taken last month. HOW IS HE NOT AGING?! (Pics: PA Photos)

12. ZAYN

In the six (!!) years since Zayn Malik won our hearts on The X Factor, he's buffed up, grown out the facial hair and chopped off those dark locks. But one thing will NEVER change... that smize! (Pics: PA Photos)
