The Britain's Got Talent judge announced last week that she is expecting her first child with dancer boyfriend Azuka Ononye.
Surprisingly, her pregnancy wasn't actually mentioned during her TV appearance until the very end, when she confirmed that she is indeed "very happy" to be expecting a child.
Alesha was joined on the show by Emma Bunton to promote their new Saturday night series Your Face Sounds Familiar.
The series will begin this Saturday, 29 June, and challenges celebrities to perform as different music stars each week. In a twist, they won't have any say about who they perform as, or whether they are male or female!
Celebrities involved include Denise Lewis, Matt Johnson, Bobby Davro and Cheryl Fergison, while Emma will judge alongside Julian Clary and Alesha will host with Paddy McGuinness.
While Alesha's pregnancy wasn't really discussed today, another pregnancy was: that of Paddy's wife Christine.
Phillip Schofield pointed out that Paddy has publicly said if Christine goes into labour with their twins while the show is on air he'll dash off to be by her side. "And rightly so!" said Alesha.
It was confirmed today that Stephen Mulhern will be on hand to cover for Paddy should the Baby McGuinnesses make their arrival half-way through the show.
