Hilary Duff put the rumor mill in overdrive again when it comes to her relationship with Mike Comrie. The separated couple has been caught spending a lot of time together, both with son Luca and without.

"I don't think Mike would ever go anywhere," Duff told Us Weekly at the ASPCA Cocktail Party. "I mean, we are really dedicated to taking care of Luca, and we're really good friends who spend a lot of time together."

"We're not in a rush for anything," she added. "So we're just trying to enjoy our lives and figure out what makes us happy and it's working for us."

The former Disney star looked ravishing in black leggings, a pattern top, and deep red lipstick. She announced her split from Comrie in January, but fans have been speculating their relationship status since they were seen on vacation together.

Duff and Comrie were also seen enjoying Coachella alongside each other.

"We have Luca as our main priority," Duff explained. "But we do care a lot about each other. We're adults and we're making our way through life. Sometimes you do that together and apart and we're gonna be and we're going to do it in the most peaceful way possible."

The "So Yesterday" songstress also praised 2-year-old Luca and her sister Haylie's fiancé Matt Rosenberg.

"He's two!" Duff gushed of her baby boy. "So he definitely has a strong personality!" 

"He opened his own door today, I couldn't believe it! I was like, 'Wow, when did that happen?' Like when he can actually twist the doorknob and push the door open?"

When asked about her older sister's upcoming nuptials, Duff told the mag the plans have just started and the family loves Rosenberg.

"Actually we just started," she admitted. "We don't have a date or anything, but she's starting to throw out ideas for venues and she's obsessed with Pinterest. It's exciting."
