FORMER Charters School pupil and Great British Bake Off star Martha Collison has announced she is engaged.

The celebrity baker, 20, who has released two cookery books in recent years, took to social media on Sunday to share her good news.

She posted two pictures on Twitter showing herself and her fiancé Michael Haywood on the beach in Brighton where her beau had seemingly just popped the question.

In one of the photos, Martha is seen holding up a sign which reads ‘She said YES!’ and dated January 25.

The former Charters School Head Girl, who appeared on the BBC series in 2014 while studying for her A-Levels, captioned the post: “He decided 3 years together wasn’t quite enough, so he asked for a lifetime. And I said YES!”

She tagged her new fiancé in the caption, adding: “@mbhaywood27, I can’t wait to be your wife!”
