Though Hilary Duff and her ex Mike Comrie have remained friendly exes
up until this point, that may be about to change.
The 27-year-old Younger actress
asked for primary physical custody of their three-year-old son Luca with visitation rights for Comrie in her divorce filing in February, but the former hockey pro is seeking joint legal and physical custody of their only child in his response filed on April 17.
Comrie also asked that their assets and property be divided based on the terms of their prenuptial agreement. The two tied the knot in August 2010, but announced their separation in January 2014.
Up until this point, Hilary and Comrie, 34, have remained close -- they even came together
to throw a birthday party for Luca last month.
"Cutest Dad-to-be & Dad around! @mattyrose3 & Mikey," Hilary's pregnant older sister Hailey captioned this Instagram pic of her fiance Matt Rosenberg carrying a tray of cupcakes with Comrie.
Hilary has touched on her relationship with her ex before, saying she was "proud" of the way they've handled their breakup so far.
"It wasn't working well enough to stay together, but there was still a lot of love involved," she told Cosmopolitan last month. "It was just a slow set-in of us not being the match that we used to be. I'm lucky for the person he is and I am, and how we decided to handle this."
Still, despite any potential looming divorce drama, the "All About You" singer is looking better than ever. Hilary flaunts her toned abs on the May 2015 cover of Shape, rocking a colorful ruffled bikini, denim cut-offs, and throwing a demure pink cardigan over the sexy ensemble.
"Love @shape_magazine and was so honored to be on the cover!" she Instagrammed on Wednesday. "It's the May issue! Go pick it up this Tuesday!"
The petite star opened up about body image to ELLE
"I just tell myself, 'I'm 5'2", I'm really fit, killing it in the gym, and doing crazy things,'" she said. "I love to work out, but I'm just not that concerned with being the skinniest person. I'm not a model; I'm an actress. I always feel like I'm in the five to ten pound struggle, but my life is so busy."
