Soul singer Lionel Richie's 18-year-old kid has been unveiled as the face for an upcoming campaign with fashion brand PrettyLittleThing.com.

The collection, called PrettyLittleThing Starring Sofia Richie, will launch on Halloween (31Oct16).

Sofia and Justin dated this summer (16) but split in September. During their time together, Bieber whisked the teenage beauty off to Japan for his run of shows there and then they celebrated her 18th birthday together in Mexico.

During an interview with Billboard.com, Sofia said, "We have a special relationship. Justin is very easy to talk to, and that's hard to find with people in Los Angeles."
