Feel like you’ve put on a few pounds after the Christmas excess? Fear not, you’re in good company.

Australian supermare Black Caviar has bulked up and can reportedly no longer fit into the famous compression suit that she wore to travel to England in June 2012.

The hefty mare has tipped the scales at 610kg — 70kg more than her racing weight last summer, after six months off.

“She’s always been a ‘good doer’,” part-owner Pam Hawkes told H&H after her visit to Royal Ascot.

“She has a bit of a weight issue — she’d be like ‘Ten-Tonne Tessie’ in a flash if you let her.”

The unbeaten mare — who has won 22 races in a row — hasn’t run since Royal Ascot in June and is due to contest the Black Caviar Lightning Stakes at Flemington on 16 February.

There will be a lot of work to bring her back in to shape.

But trainer Peter Moody gallantly leapt to her defence, saying: “She’s not fat, she’s just a bit overweight.”
