Her fans flooded in with comments raving about the star. One wrote: “Love it! You made me laugh like you were on holiday and not at a race.”

A second added: “I’m really enjoying the show so far and can’t wait for next week.”

“Really enjoyed watching the show. You two are the best xx,” wrote another.

Kelly had previously surprised viewers on Wednesday by revealing her real name in the opening episode of the BBC show.

The presenter was born Kelly Anne Parsons but took the surname Brook when she started her modeling career.

Although this is the name by which she is known, it was never entered on her passport.

This comes after Kelly surprised viewers by revealing her real name in the opening episode of the BBC show on Wednesday.

She said: “My happy place is my garden, in wellies, no make-up and with my hair up. When I think about how I was like a pin-up and making calendars, it’s all just an illusion, like that’s not who I am at all.”

“Kelly Brook doesn’t actually exist, it’s not even a real name, it wasn’t even on my passport or anything. In my mind I’m Mrs. Parisi, Jeremy’s wife.”

The star recalled the “honeymoon from hell” in a recent interview when she spoke about the challenge.

After mistakenly believing the arduous 12,500km journey through South America was an alternative honeymoon, Kelly told Closer magazine: “We haven’t had a honeymoon before and I said to Jeremy we should think of this as a fun alternative, once in a lifetime experience. Sometimes they were the honeymoon from hell – sometimes they were just glorious. They have to be the most unforgettable honeymoons ever!”

She described in detail how the trip helped them understand the dynamics of their relationship, continuing, “I didn’t realize how ambitious he was, like, insanely ambitious. For me, it’s much more about the experience.”

“I think I got on his nerves because he was full steam ahead. If Jeremy had done the race alone, he would have done it in a week. I slowed him down a bit and said let’s have a Brazilian barbecue one day or go to the beach.
