The Love Actually star confirmed he’s engaged to the actress via Instagram on Thursday — and gave a sweet nod to one of his signature roles.
“Happy to announce that Talulah and I are engaged. Love is all around,” wrote the actor, 33, quoting a line uttered by Hugh Grant’s Prime Minister in the 2003 Christmas classic (not to mention a lyric from the Troggs song holiday-ified by Bill Nighy’s Billy Mack in the movie).
Riley, 37, also shared the news on Twitter alongside a cuddly photo of her with her now-fiancé.
“Very happy to share that after two years of dating, Thomas Brodie Sangster and I are engaged!” she wrote.
