The ladies were snapped at the star-studded TV Choice Awards in London and Charlotte looked simply dazzling in a gold sequinned dress.
Breakfast host Charlotte is expecting her first baby and announced her pregnancy on Twitter last month, before later confirming it on air.
There is no mistaking her baby bump now and Susanna was clearly excited to help show it off to the world at the glitzy ceremony, which was held at the Park Lane Hilton.
Before heading off, Charlotte and Susanna - who also looked sizzling in an asymmetric red dress - posed for a picture alongside their GMB co-stars, Ben Shepherd and Sean Fletcher.
Sharing the picture on Twitter, 39-year-old Charlotte told her followers: "Team @GMB on the way to the @TVChoice awards tonight!"
Charlotte has been married to her businessman husband Mark Herbert for five years. The couple were dating for a decade before tying the knot.
Meanwhile, Charlotte wasn't the only star sporting a baby bump at the TV Choice Awards.
EastEnders actress Jacqueline Jossa showed off her tiny bump in a midnight blue dress, while Coronation Street's Catherine Tyldesley dressed her pregnant tummy in a figure-hugging red frock.
