Sophie announced the engagement by showing off her new ring on Instagram, with the caption "I said yes."
The pair have reportedly been dating since last fall.
Joe's brother Nick seemed to confirm the engagement when he posted the photo of Sophie's ring with the caption, "Ahh! Congratulations to my brother... and sister in law to be on your engagement. I love you both so much."
Back in July, Sophie told the Sunday Times that she was "in a relationship, but it’s a very private relationship.”
She also told InStyle back in July that she "found it easier to date someone who understands the industry or is in that world."
Congratulations, you two!
