The 24-year-old reality TV star joined the winter sports show late as a replacement after Vogue Williams was forced to pull out due to a knee injury but she has admitted she's got stuck in to the challenges because she's determined to win the series.

Speaking to Star magazine, she said: "The ski cross got me the most battered and bruised. I've literally been flying more on the slopes than I have on the actual jump. The stress has made me lost a bit of weight, even though we eat so much good. We're on the mountain diet so we're constantly carb loading."

And, although she's been riddled with injuries over the past few weeks, the blonde beauty - who also did 'I'm A Celebrity... Get Me Out of Here!' a few years back - believes the Channel 4 ski series is the "best show" she's ever signed up.

She explained: "It's been amazing. It's definitely the best show I've ever done."

However, Amy is starting to miss her boyfriend - even though he's visited her in Austria.

She said: "He's been out a quite few times. Bradley Wiggins - who was was forced to pull out of the programme due to injury - joked that Dan is in Austria more than him."

The couple are very much loved up but Amy has no plans to tie the knot just yet.

She added: "It [marriage] comes up in a jokey way. I'm on 24 so I'm in no rush to settle down. Don't expect to see me in a white dress tomorrow, let's put it that way."
