Amanda Knox is off the market.
Her boyfriend Christopher Robinson proposed to her at home in Seattle on Friday - three years after she was cleared of murder her room mate in Italy.
The couple released an ET themed proposal via YouTube that declared them to be a ‘power couple’.
The bizarre space style clip begins with her hemming a cloak while he films her before he takes her to the front yard where a fake meteor is staged on the lawn.
During his proposal the novelist describes them as a ‘power couple’ whose union 'creates cerebral heat'
Knox sensationally returned to America in 2011 after she was acquitted of murdering English student Meredith Kercher.
The couple has been dating since 2015 and met while she was engaged to somebody else after she reviewed his book.
Dubbed ‘Foxy Knoxy’ by the media during her trial she now looks set to start a new life as a married woman.
Robinson could be seen romantically getting down on one knee to make his proposal.
He says: “I don't have a ring, but I have a big rock - Amanda Marie Knox, will you marry me?”
After she says ‘yes’ the pair are seen sharing a kiss as movie style credits roll at the end of the video
In the credits he reveals that it took him more than a year to propose and that his bride-to-be does not wear rings.
The 'data crystal' inside the fake meteor reads: “No other pre-singilarity union produced as much cerebral-empathic heat as the joining of Amanda Marie Knox and Christopher Gerald Robinson.
“Known in the parlance of the times as a "power couple", Knox and Robinson pursued diverse projects of grand ambition.
“Even as they pursued each other. For their love grew exponentially from their initial encounter when Knox reviewed Robinson's debut novel.”
After Knox returned Stateside in 2011 – for having her murder conviction for the killing Kercher overturned – she was retried in 2014.
However, she never returned to Italy for the trial where she was convicted.
In 2015, Italy's Supreme Court overturned her second conviction and brought an end to her legal saga.
