"Hi, you look amazing," Bloom, 37, said to the gorgeous supermodel as he gave her a kiss on the cheek. "Are you well?"
Kerr, 30, wearing a metallic silver gown, flashed her trademark dimpled smile at her ex-husband as she replied, "Yeah, yeah."
Bloom then walked away to pose for photos while his ex-wife continued the segment like a true professional. "I think Cate Blanchett always looks so beautiful," she said of her fellow Aussie, who took home the Best Actress Oscar for her role in Blue Jasmine.
The latest run-in is nothing new for the separated pair: Bloom and Kerr also attended the same Golden Globes after party back in January, where an eyewitness told Us that the Hobbit actor was "hitting on a lot of girls."
As confirmed by Us Weekly back in October, Kerr and Bloom confirmed their split after three years of marriage. The parents, who share son Flynn, 2, announced through their reps that they had "amicably separated" months before and "love, support, and respect each other as both parents of their son and as family."
Following their split, the two have been photographed playing with their son and getting along great. "I'm completely in love with the idea of love. Maybe I'm all misty about it because I'm playing Romeo," the actor said to Elle magazine in its January issue. "But I really believe in, you know, that sort of heart-to-heart-connection."
