Hilary Duff graces the cover of Cosmopolitan's April 2015 issue, looking like a total badass in an low-cut, black leather jacket that shows off all of her curves.

In the mag's newest issue -- out March 10! -- the Younger actress gets candid and completely honest about her relationship with her ex-husband Mike Comrie, her life after divorce, and yes, the "ridiculous"-ness of those Aaron Carter tweets.

"Mike and I were very in love when we met. We both really wanted to get married. I'd been working since the age of 11 or 12, so making that choice at a young age seemed right for me. Maybe it wasn't, but we spent the majority of our time together really happy," the "All About You" singer said her marriage to Comrie. "It wasn't working well enough to stay together, but there was still a lot of love involved. 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."

While the two are still good friends and are awesome co-parents to their young son Luca, the divorce has changed Duff's view on love and relationships.

"I don't want to sound bitter because I'm definitely not, but I don't know if people are meant to be together forever," she told the magazine. "Things happen over a long relationship that you can't always fight. A marriage of 20 years, the accomplishment of that must feel really great, but there are also huge sacrifices. I just always want to fight for happiness."

Speaking of happiness, something that puts a smile on her face is her sultry summer hit, "All About You."

"I wrote that song for a reason! I've enjoyed myself," Duff revealed. "I think everyone should have something where you know it's not exactly what you're looking for but you just have a wicked good time. That was really freeing for me and a bit of an awakening. It's fun to have a secret."

Still, maybe some people's secrets should be kept as such -- like Aaron Carter's over-the-top declarations of love for Hilary Duff.

"Him reaching out through social media? It's ridiculous!" she told the mag. "But then people do it all the time, like Chris Brown and Karrueche? Come on, guys. Keep it between text messages."
