Bodyguard star Keeley Hawes has dismissed claims she went on a diet in preparation for her steamy role in the hit BBC drama.

The actor, who plays a fictional Home Secretary in the series, shared a Mailonline article about herself, which claims she lost a stone by doing the alkaline diet. 

In a tweet she said: “Um, no, I didn’t.”

She added in a hashtag that she didn’t know what an alkaline diet was.

In the article, the Mail On Sunday’s Katie Hind, who is currently editing the paper’s Talk of Town diary said: “I hear she lost about a stone for the part, putting herself on an alkaline diet and an exercise regime based on the methods espoused by US fitness guru Tracey Anderson.

“My source on the TV show’s set said: ‘This is a really sexy role for her, she wanted to get in character and look amazing.’”

The actor’s tweet was praised by fans for calling the article out.
