Actress-singer Myleene Klass has the "Littlewoods touch" in a commercial for the U.K. retailer that features a song with bright pop melodies and gentle cooing from a female voice. What's the name of that song?

While Klass has released a couple of her own solo albums, the song in the ad comes from Danish pop singer Nanna Øland Fabricius, better known as Oh Land. The track, called 'White Nights,' appeared on her 2011 self-titled release, which was a smash in Denmark and cracked the Billboard 200 albums chart in the U.S., reaching No. 5 on the Heatseekers tally.

'White Nights' was issued as a single in Denmark and went gold. Oh Land is perhaps best known in America for appearing on 'Life Goes On,' a track on the most recent album by hip-hop-influenced pop-rock band Gym Class Heroes. She also scored a No. 12 dance hit with 2010 single 'Sun of a Gun.'

'White Nights' adds vibrant musical highlights to the colorful commercial, in which women playing in a park in autumn see their outfits instantly transformed into glamorous evening wear when Klass points at them with her Littlewoods magic touch. A Littlewoods narrator states that every woman can get the fashionable look she wants by opening a line of credit at the store.
