The couple, who met when they both presented CBBC a few years ago, have just celebrated their first wedding anniversary, and announced their happy news on, of course, Twitter.
'Just to let you know @MikeyUnderwood and I are having a baby! Had the scan this morning and all is well. All very exciting!' tweeted mum-to-be Angellica. 'Now you know why I've been talking about food non-stop for the past " months! Ha!'
Excited Angellica then went on to tell her 22,179 followers she had already started buying maternity goodies for her growing tum:
'Bought loads of bras for my ample breasts! Also got a maternity cream top! Lush.'
This will be the couple's first baby, and is due in December.
