You may know her from Britain's Got talent or Alesha's Street Dance Stars but did you know she's also a pop star?
Alesha Dixon has achieved some pretty impressive feats since she first rose to fame over 15 years ago.
From winning Strictly Come Dancing to climbing mountains for charity.
We take a look back at some of her career highlights so far.
Alesha rose to fame in the late nineties as one third of girl group Mis-Teeq, often rapping on their songs.
She lifted the Strictly Come Dancing trophy in 2007 with her professional partner Matthew Cutler.
And returned to the show as a judge for three series from 2009-2011.
In 2009, she co-presented Children in Need with Terry Wogan and Tess Daly.
And in the same year she took to the stage to perform at Radio 1's Big Weekend in Swindon.
But it didn't stop there because in 2009 she also conquered Mount Kilimanjaro, the highest mountain in Africa, for Comic Relief.
Alesha then danced her way onto CBBC in 2011 with her programme Alesha's Street Dance Stars.
And now millions of people around the UK watch as people try and impress her with their hidden talents on BGT.
