It was revealed earlier this week that she is pregnant with her first child with dancer Azuka Ononye.
A spokesperson for the Britain's Got Talent judge announced the happy news in a statement on Thursday afternoon (June 20).
And now Alesha has broken her silence by thanking her fans for their congratulations.
She tweeted: "Would just like to say a big THANK U for all of your lovely messages and well wishes! #verysweet #veryblessed :) X."
The baby is understood to be due in December, with Alesha expected to return to the judging panel on the eighth run of BGT soon after.
We think Alesha and Azuka are going to be the cutest parents ever!
