It's the wedding of the year.
Pippa Middleton is marrying James Matthews, brother to Made in Chelsea's Spencer Matthews.
The wedding is taking place near her family home at Berkshire, west of London - and Pippa's dress is stunning!
She's wearing a dress featuring a keyhole back with lace detailing, a small tiara and veil over her face. The bride arrived to the church in an open-top vintage car alongside her father.
Prince George is page boy while Princess Charlotte is the flower girl.
Later, the bride and groom will meet 300 guests at Middleton's family home in Bucklebury for a lavish reception inside a glass structure.
