Hilary Duff showed off her bikini body as she hit the beach in Maui, Hawaii on Feb. 4.

Her ex-husband Mike Comrie and their son, 3-year-old Luca Cruz Comrie, joined the 28-year-old.

Hilary has reportedly said she will always be on good terms with her ex, and this trip was perfect proof of that. The pair's divorce was finalized just a week before they jetted off on a vacation together in Hawaii.

The "Sparks" singer was spotted wearing a stripped bikini full of colors, such as yellow, black, red, pink and blue. The triangle top designed by Solid & Stripped was worn with matching bottoms and paired with brown sunglasses.

The two-piece showed off Hilary's super fit mom body.

Hilary and Mike, who began dating in 2007, got engaged in February 2010 before tying the knot just a few months later in August of that year. The pair welcomed their son in 2012 and announced their amicable separation in January 2014.

"They remain best friends and will continue to be in each other's lives," Hilary's rep said in a statement via E! News. "They are dedicated to loving and parenting their amazing son, and ask for privacy at this time."

At the time, Hilary also addressed the parting of ways on Twitter and reiterated that she and Mike will remain close.

"Mike and I are sitting here, we are so appreciative for all of your kindness & well wishes," she tweeted. "Not an easy day but we're getting thru it together."

A source told People Magazine that "there was no major incident -- no big event between the two of them. They really did drift apart. They have put effort and thought into this decision for a long time. They tried couples therapy, but in the end, they realized at this time, they work better as friends. And they really are great friends."

The pair has clearly lived up to their "amicable" promise and have been spotted together often, even after the singer-actress filed for divorce in February 2015.

Details of their finalized split were released earlier this week. Hilary will be required to pay $2,408,786 for half percent of the value of their Beverly Hills mansion, which she will keep. The singer will also get to keep her interest in their mobile home. Meanwhile, Mike will get a 2014 Bentley coupe, a 2013 Mercedes G-Class SUV and some jewelry. The couple will share custody of their son.
