Charlize Theron and Stuart Townsend have put an end to their relationship because of work commitments.

Theron, who has dated Townsend for the past five years, was seen without her beau at recent events like the BAFTAs and the Academy Awards.

"Charlize is free and single again. Her relationship with Stuart is well and truly over. They just grew apart," an inside source revealed. "It wasn't always easy because filming often kept them apart for months."
