The Britain's Got Talent judge is expecting her child with her dancer boyfriend Azuka Ononye and they are said to be "delighted".
In a statement, her rep said: "Alesha Dixon 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.
"Further details will be given at the appropriate time."
Alesha is said to have been dating Azuka for several years, however she has managed to keep her relationship secret and away from the public eye.
She was previously married to So Solid rapper MC Harvey but the couple did not have any children together before their split in 2006.
Speaking about her private life, Alesha recently said: "There's a fine line between what's necessary for work and what happens outside of that.
"That's my business and my life and no one needs to concern themselves with it."
Congratulations, Alesha and Azuka!
