The `Britain`s Got Talent` judge is expecting her first child with dancer Azuka Ononye, who she met in 2006 when he was hired as her backing dancer and the pair become close when he worked with her again in 2010.
A spokesman for Alesha said: "AleshaDixon and her partner, Azuka Ononye, are delighted to announce that they are expecting their first child later this year.
"Alesha and Azuka are looking forward to this happy chapter in their lives and would request privacy to enjoy this happy and most important event."
Alesha was previously married to So Solid Crew member MC Harvey, real name Michael Harvey Jnr, who she married in 2005 but their marriage ended in 2006 when it was revealed he cheated on her with singer Javine Hylton.
The 33-year-old singer`s career has gone from strength to strength since she appeared as a contestant on BBC ballroom dance show `Strictly Come Dancing` in 2007 when she won the series before joining the judging panel two years later as a replacement Arlene Phillips.
Alesha then joined rival programme `Britain`s Got Talent` alongside Simon Cowell, David Walliams and Amanda Holden.
