The model has signed a £250k deal to replace Michael Buble's wife Luisana Lopilato, who has reportedly left the job to focus on her son, Noah.
Abbey said in a statement: “It’s really exciting to be part of such an established brand at such an exciting time.”
This weekend she and Corrie actress Natalie Gumede received the joint best scores in the Strictly semi-final.
They both won 78 points and each received a maximum 40 out of 40 for their first dance.
An over-the-moon Abbey tweeted:

Patrick Robinson was voted off the show on Sunday, meaning it will an all-female final next weekend with just Sophie Ellis Bextor, Abbey, Susanna Reid and Natalie remaining.
