Former Chancellor George Osbourne proudly showed off his baby son at the 'Downton Abbey' wedding of TV chef Clodagh McKenna and Harry Herbert.
Little Beau arrived in London on July 14, weighing 6lb 9oz.
Mr Osborne, 50, and his fiancée Thea Rogers, 39, were proud as punch with their plus one at the star-studded wedding in Highclere Castle, Hampshire.
The couple, announced their engagement in April.
Dressed all in blue, Beau was proudly displayed by his smiling father and mother.
Irish chef, Clodagh, 46, wore a lace gown at her wedding ceremony, while 62-year-old Harry, the Queen's Godson, wore a morning suit, cream waist coat and tie.
The newly-weds got married at the 5000-acre estate and share Broadspear House, a 300-year-old cottage in grounds of Highclere Park.
Harry was born in Highclere Castle and his family has owned the impressive estate since the late 17th century.
His father Henry was a longtime close friend and racing manager to Queen Elizabeth II from 1969 until his death in 2001.
Her Majesty reportedly called Henry 'Porchie,' affectionately based on his title, Lord Porchester and he is seen appearing in the first two seasons of The Crown played by Joseph Kloska.
Friends at the wedding were delighted to see Mr Osborne and his fiancée Deliveroo executive Thea Rogers following Beau's birth.
George, 49, met Thea, 39, two years ago, and friends described the couple's mood as "thrilled and excited" following their son's birth.
The couple were photographed together with their new son sharing a laugh with wedding guests at the grand setting.
Thea was Mr Osborne's Chief of Staff while he was Chancellor and previously his special adviser.
