Miley responded by commenting under the post with nine black hearts.
And her mum Tish also gave her approval of Miley and Cody's blossoming romance, as she responded: "Puts a smile on my face too @angiemsimpson love you my sweet friend."
"Soup is an aphrodisiac," she boasted in the caption.
Miley also shared a sweet selfie of the pair all dressed in black in a bathroom together.
The singer's social media shares could be a response to her soon-to-be-ex husband, Liam Hemsworth, as he has been spotted out with his new girlfriend, Maddison Brown.
TMZ captured the Australian hunk on a date with the blonde up-and-coming star, taking her on a romantic stroll and for dinner in NYC's West Village neighbourhood on Thursday.
Miley and Liam split in August 2019, with the singer soon dating Kaitlynn Carter.
Kaitlynn and Miley's relationship lasted just weeks, and then earlier this month the Wrecking Ball singer announced she was in a relationship with her longtime friend Cody Simpson.
"I’m very happy. We are very, very happy," Cody revealed to People over the weekend.
"She’s creative. She’s very passionate about what she does, and I’m very similar in that sense," he added.
"That’s why we get along so well. We just have a ball, yeah, and that’s the most important part of a relationship, you know?" he concluded.
He added that he and Miley had known each other for a long time and that they "found each other again in a space where we’re both not partying, working real hard, and it just keeps things healthy and it’s good."
"Any girlfriends I’ve had in the past has always been immediate romance and so it’s a different experience having been friends with somebody before and it developing naturally into something more," he told the publication.
