A former RangersWAG stuck the boot into Celtic captain Scott Brown after her husband's old side won their Old Firm derby – before sharing a very revealing snap.

Brittany Polster, the wife of former Gers defender Matt, uploaded a video of her playing with the "which footballer are you" filter on Instagram.

Hours after Celtic lost to Rangers in the crucial Glasgow derby, the answer came back with the Hoops skipper.

Brittany, clearly enjoying the moment, joked: "Oh FFS. Happy derby day."

Soon afterwards the blonde delighted her 16,400 followers when she uploaded a racy photo of herself stripped down to skimpy lingerie to celebrate her first wedding anniversary.

She added the caption: "BTS Wedding Day. Cannot fathom that we've been almost married 1 year. T-2 sleeps."

One of the replies came from another ex-Rangers girlfriend Jilly Isabella, partner of former Gers star Andy Halliday, 29.

She wrote in capitals: "Divorce Matt marry me."

Brittany's cheeky response said: "Done. Where's my ring? We'll leave the boys to themselves."

Rangers fans were gutted after Polster's glamorous wife, who lit up Ibrox, said goodbye in July 2020.

Brittany Polster was quick to mock Scott Brown after Celtic's derby defeat to Rangers

American international Polster, 27, signed for Major League Soccer side the New England Revolution because he was struggling to command a place in Rangers' team 18 months after signing.

Brittany was a regular presence at home and away games, often wearing the jersey with her husband's name and number on the back.

She was even known to enjoy a pint at the Louden Tavern pub around the corner from Ibrox before the coronavirus pandemic sent football behind closed doors.

Biding farewell, Brittany said: "Goodbyes are never easy. So this is a post of gratitude & love.

"To the club, staff, teammates, families, supporters, & people of Scotland. You’ve been engrained on our hearts forever.

"You are the heart & soul of this city. To every person who took the time throughout our stay, to stop us & ask how we’re finding the move, city, weather, our new lives, the club...thank you for caring.

"Thank you for loving us as one of your own. I can only hope you continue to support Matt in his career and love us from afar.

"This has been the journey of a lifetime. Until we meet again. WE ARE THE PEOPLE."

She also regularly posts scantily-clad snaps on social media showcasing the couple's glamorous life together.
