Hilary Duff shot scenes for her TV series Younger in New York City on Thursday, the day after she called Aaron Carter’s professions of love “uncomfortable.”

Duff, 27, hit the streets of Manhattan for her day on the Younger set in a pale blue miniskirt and denim jacket. She accessorized with a Chanel bag and wore her long blond hair in a loose wave.

In Younger, Duff plays a 20-something trying to work her way up at a publishing firm. She soon meets a new co-worker named Liza (Sutton Foster), who is trying to appear a decade younger than she is for the sake of her career. Soon, Duff’s character Kelsey befriends Liza and tries to help her fit in and assimilate to the younger people at the office.

Duff Addresses Aaron Carter’s Ongoing Love

While appearing as a guest on Andy Cohen’s Watch What Happens Live to promote the show, the host couldn’t help but ask Duff about her former boyfriend Aaron Carter during the “Plead the Fifth” segment. “Really? Andy! I’m going to hurt you right now,” said Duff before launching into her answer.

“I don't know. I don't know what to say about it! It was so many years ago,” Duff said, adding, “I literally haven't seen him in… so, it's uncomfortable.”

When fellow guest Food Network star Giada De Laurentiis, who didn’t know about the former romance, asked if they’d dated, Duff answered, “Yes, when I was 13. He was very sweet… when I was 13.”

Cohen chimed in, “He’s just feeling you on Twitter, publicly,” to which Duff replied, “It’s nice to be felt.”

Back in March, Carter vowed to win Duff back, over a decade after the two called it quits for good. The young love ended when it came out that Carter was two-timing Duff with fellow teen celebrity Lindsay Lohan, which Nick Carter’s little brother has grown to regret.

“I'll spend the rest of my life trying to better myself to get back to her,” Carter tweeted. “I don't care what ANY of you think.’
