It looks like Hilary Duff is most definitely a single lady again. The former child star was photographed without her giant diamond wedding ring and accompanying bands while running errands on Monday, Jan. 13. 

Though she'd clearly taken off her ring, Duff, 26, looked upbeat and trendy as ever while out with her adorable son Luca. The "Coming Clean" singer visited a friend's house and made a trip to the gym. 

Duff announced her split from husband of three years Mike Comrie on Friday, Jan. 10, but the couple has since been spotted out together, having a weekend brunch with their 21-month-old son on Sunday, Jan. 12. 

In the photo of the couple driving back from the weekend outing, Comrie, 33, didn't appear to be wearing his ring either. 

In a statement from Duff's rep about the split, the Gossip Girl star said she remains "best friends" with the former NHL star, and the two are "dedicated to loving and parenting their amazing son."
