Boris Johnson's girlfriend Carrie Symonds walked into Number 10 alongside him in her first 'official' moment as the Prime Minister's other half.
Despite making a number of appearances since news of their relationship broke, the 31-year-old PR guru normally stands at the sidelines rather than by his side.
Carrie, who is 23 years younger than the Prime Minister and is said to call him Bozzie Bear, met Johnson while working in the Conservative Party's communications team.
She is the first unmarried partner of a Prime Minister to live at the famous property, although the couple have actually set up home above Number 11 rather than the tradition residence.
Carrie made her first appearance as Johnson's partner when he launched his leadership campaign for Number 10 back in June, however she stood to the side as he made his speech.
She also stood outside when he walked through the front door for the first time after his victory.
But this morning Carrie beamed and waved as she walked through the famous black door by her boyfriend's side.
She wore a beige coat over a green shirt and black boots, while Johnson opted for a black suit and red tie.
The couple have been together since last year, when Mr Johnson's wife Marina reportedly kicked him out of their shared home following the affair rumours.
She has been credited with revamping his image in the lead-up to the leadership contest, including a new smarter haircut.
The couple lived together in his £1million flat in South London before moving into Number 10.
Carrie is an environmental campaigner who was named one of Britain's most powerful PR experts in her Tory role.
She quit her high-flying job as the Tories' Director of Communications last year and she has since joined Bloomberg.
She was also praised after speaking out about her ordeal as one of the youngest victims of taxi driver rapist John Worboys, aged 19.
She said after waiving her anonymity in 2009: “He is a sad, wicked man who is a danger to society.”
While she played no role in Johnson's leadership campaign, she masterminded the grassroots operation for Theresa May ’s 2017 General Election - which was a flop, with Mrs May losing her majority.
