Model shows off more athletic body on US TV show

Rachel Hunter unveiled a curvier look on a US reality television show last week.

The model, who was previously a spokeswoman for Slim Fast, is appearing on Celebrity Circus – and taking part in the challenging tasks means she’s put on some extra muscle.

It marks a stark contrast to how Rachel, 38, looked in November 2006 (below).

Rachel was married to Rod Stewart, 62, for 9 years from 1990. They have 2 children – Renee, 15, and Liam, 13.
