Arriving in Liverpool for a solo engagement, the Duchess of Cambridge looks every inch the professional royal in elegant and professional attire.
And although she's on duty and without husband Prince William on the most romantic day of the year, her Valentine's Day still had a touch of romanticism about it.
Kate was presented with a cupcake by eight-year-old, Jaqson Johnston-Lynch during her visit to Brink, the city's dry bar for recovering alcoholics.

The sweet treat was crowned with a heart that reads "Jaqson loves Kate".
"I'm going to say 'Happy Valentine's Day, your Royal Highness. I'm sorry Prince William can't be here' " Jaqson said, before presenting the Duchess with a bouquet of red roses and a Valentine's Day card.
"I wrote in the card 'Dear Kate, Happy Valentine's Day, I love you, from Jaqson' ".
The brunette's young admirer was chosen to greet her because his mum, Jacquie Johnston-Lynch, is the head of service at affiliated charity, Action on Addiction, of which Kate is patron.
During the visit the Duchess served non-alcoholic drinks to regulars, one of which is a smoothie named after her.
Brink's resident choir, the Raucous Caucus Recovery Chorus, serenaded their VIP visitor with a rendition of Wings Of A Dove.
Michael Edwards, who is a member of the group, said of their choice: "It's a song about hope and happiness. I got involved in the choir because I'm in recovery from drugs and alcohol."
"It's a bit scary with a royal audience but this is what the choir has done for me, to give me the confidence to sing in front of people."
After Kate's turn behind the bar, she moved on to meet young patients at Alder Hey's Children's hospital.
