Mollie and pro partner AJ Pritchard kicked off their Strictly journey last weekend with a Jive to Good Golly Miss Molly by Little Richard
The routine got a mixed reception from the judges with Craig Revel Horwood branding Mollie "awkward" and awarding just four points.
Speaking about her debut performance this week, The Saturdays singer said: "It was terrifying... I absolutely loved every minute of it it though.
"I think I loved it a bit too much because the hands were going everywhere, the arms were going everywhere, even the legs were going everywhere.
Despite the somewhat harsh comments from the judges, AJ was positive: "For me it was fantastic, she was on her own a lot of the time.
"I put her under pressure and for me, it was fantastic."
In tonight's second live show, the pair will dance the Tango to Addicted To Love by Tina Turner.
And while Mollie may have the moves down, she has a big problem with the serious 'tango face'.
Smiling Mollie told It Takes Two she was struggling to keep a straight look and quipped: "My teeth keep coming out!"
Meanwhile, Mollie joked that the Strictly 'curse' may have already claimed a victim.
She told the BBC Two spin-off show, hosted by Zoe Ball, that the 'man' currently in her life - dog Alfie - was getting jealous of AJ,
"AJ came over to watch the coupling show at my house," Mollie said, "And Alfie got a bit jealous like: 'Who is this man in my flat?'"
Strictly Come Dancing 2017 returns to TV tonight at 6:45PM on BBC One.
The results air on Sunday night from 7:15PM.
