Tell us about your involvement in Sweat The Small Stuff?

I'm the only resident girl so I'm there to rein the boys in when they get out of hand!

What do you 'sweat' over?

At the minute, I'm sweating over hormones because I'm pregnant!

What are you most looking forward to about being on the Sweat The Small Stuff panel?

Having a laugh with the boys.

Do you have a favourite round on the show?

I like the round where Rickie and Melvin compete against each other.

Who would be your dream guest on your team?

Harry Styles - so we could gang up on Grimmy!

Do you prefer working in TV or in the music industry?

Music.

Who do you prefer - Rickie or Melvin?

Well I'm on Rickie's team, so I have to say him!

You're about to give birth - are you happy for the boys, Nick, Rickie and Melvin, to step in as midwife if your waters break in the studio?

Yes! Someone needs to help me..!
