Gallacher, who moved from Scotland when she was 18 months old, will be backing the Lionesses when they take on Scotland in the opening match tonight.
She said: “We are all extremely proud of the England team. I hope the chants help inspire the public to get behind the Lionesses.”
The English team’s sponsors Vauxhall added: “Although Kirsty was born in Scotland she has always been passionate about supporting England.
“She follows both teams but would call herself an England fan – hope this clarifies the situation.”
