The track is the singer-songwriter's first new material since 2004's Second First Impression.
The video features Bedingfield working on the song in his bathtub, before several women in underwear attempt to rip off his pyjamas.
Bedingfield is planning to self-release a new EP in 2012, after suffering several setbacks with his record label Polydor in recent years.
The New Zealand-born singer and brother of Natasha Bedingfield scored three number one singles in the UK and was named 'Best Male' at the 2004 Brit Awards.
