Keira Knightley is one blushing bride-to-be.

While visiting Good Morning America on Friday to promote her upcoming film, Anna Karenina, the 27-year-old actress clearly couldn't contain her joy over being betrothed.

After GMA cohost Elizabeth Vargas congratulated Knightley on her engagement to Klaxons keyboardist James Righton, the smiling Oscar-nominated star said, "Thank you. I keep doing this (waves left hand). It's the engagement shuffle."

But don't expect the couple to tie the knot anytime soon, as Knightley revealed they haven't set a date yet.

"We're both working too hard, so I'm just enjoying this bit," she said while again adorably waving her left hand.

Meanwhile, Anna Karenina opens in theaters on Nov. 16.
