The couple will live in Nottingham Cottage at Kensington Palace.'
The Kensington Palace Twitter account also shared well wishes from the Queen and Prince Phillip to the happy couple.
'The Queen and The Duke of Edinburgh are delighted for the couple and wish them every happiness,' the tweet said.
Markle's parents, Mr. Thomas Markle and Doria Ragland, released a statement congratulating the pair.

'We wish them a lifetime of happiness and are very excited for their future together.'
