"I never thought in a million years I would be here. Girl power!" Ashley said to Charlie, before heading to the Bush Telegraph.
"I can’t believe I’m in the top two, I thought David was here to the end," commented the former Pussycat Doll. "We all did, all of us, so that was left field. I’m super excited I’m here with Charlie, I love that chick to pieces."
Meanwhile, Charlie also expressed her excitement, saying: "I’m so shocked I just can’t believe it. It’s amazing, I feel so happy.
"It means a lot my family are going to be so proud, I really hope they are. Kiki will be absolutely ecstatic."
Summing up the experience, Ashley added: "It’s been a crazy experience, it’s been amazing."
