Newly solo star Nicola Roberts has confirmed that her second single will be called 'Lucky Day'. 

The 'Beat of My Drum' singer posted a message on her official website earlier this morning, August 1, that explained the track is "very different" to what her fans may be expecting, but she's excited to unveil it:

"I hope you'll like it...it's very different to Beat Of My Drum but it's important for me to show lots of different sides to my album."

'Lucky Day', which was co-produced by Dragonette, will be available for purchase from September 18, and speaking of the song itself, Roberts said:

"Dragonette were the first people I worked with when starting my album. When I wrote 'Lucky Day' I had short hair and was really into '40s fashion. All of the 'woah woah woah woah' and the 'ah ha' really is a reflection of that."

"When it came to producing the track early this year, I wanted to change it to a more modern downbeat dance record because that's what I am more into now."
