Keira Knightley can't stop showing off her engagement ring.

The 'Anna Karenina' actress - who is set to marry Klaxons keyboardist James Righton - was thrilled when 'Good Morning America' co-host Elizabeth Vargas congratulated her on her engagement and couldn't resist waving it around for all to see.

Speaking on the show on Friday (09.11.12), she said: ''Thank you. I keep [waving my hand]. It's the engagement shuffle.''

While Keira, 27, loves being engaged, the couple have no plans to tie the knot just yet.

She explained: ''We're both working too hard, so I'm just enjoying this bit.''

Earlier this year James moved in to Keira's London home, which she bought following her split from long-term boyfriend and 'Homeland' star Rupert Friend in December 2010.

A source said in April 2012: ''Keira suggested the idea and he moved his stuff in a couple of weeks ago. They want to get a puppy. It's all pretty serious.''

The couple have also recently been house-hunting for a country home.

Keira was spotted looking at estate agent details in a tea room close to where Johnny Depp bought a 13-bedroom mansion in 2011 to use as his UK base.
