Brody Jenner appears to be keeping up with ex Kaitlynn Carter.

After Carter, 30, shared a few images from her Italian getaway Friday on Instagram, Jenner, 35, commented on a photo of his former flame as she posed with Miley Cyrus.

“Hot girl summer,” Jenner replied to the snap, adding a fire emoji.

Jenner and Carter announced their breakup earlier this month following a wedding celebration in Indonesia last June. A source close to the “The Hills: New Beginnings” couple previously told Page Six that their union wasn’t legal.

As for Cyrus, a rep for the singer confirmed Saturday to People that she and husband Liam Hemsworth had split after less than a year of marriage.

“Liam and Miley have agreed to separate at this time,” a rep for Cyrus said in a statement. “Ever-evolving, changing as partners and individuals, they have decided this is what’s best while they both focus on themselves and careers. They still remain dedicated parents to all of their animals they share while lovingly taking this time apart. Please respect their process and privacy.”

Cyrus, 26, and Hemsworth, 29, wed in an intimate ceremony last December.
