"We're still best friends and I'll always respect him and support his career," she tells the publication. "I love Cody to death and he loves me."
And for the record, Hadid wasn't the one to end the relationship. "He needed his time to focus on his music," she says. "He's the one who broke up with me."
The pair went their separate ways in May after a year of dating. The couple's busy schedules and living on opposite coasts were also huge factors in the break-up.
"They remain close friends and will continue to show their support for one and other," Simpson's rep told E! News at the time.
Today, Hadid is focusing on her busy modeling career (have you seen her ads for Tom Ford?) as well as maintaining friendships with other Hollywood teenagers. One dear friend is the one and only Justin Bieber.
"Justin's a good friend of mine, he's awesome," she tells the magazine. "We know each other through my ex-boyfriend."
Bieber and Simpson are both signed to Scooter Braun and even toured together back in 2013.
"We're friends and everything with my ex-boyfriend is cool, and him and Justin are really close," Hadid says. "So it's all good."
