Zara Tindall has given fans a highly anticipated first glimpse of her newborn baby boy at the horse trials.
Lucas was pictured for the first time wearing a puffy romper with sweet bear ears as his mum, 39, took him for a day out today.
He was strapped to his mum's chest in a carrier as she tended to horses and introduced him to competitors at Houghton Hall International Horse Trials.
The doting mum-of-three then led the horses in the show with her son in tow before putting him in a buggy as she spoke with fellow equestrians.
In March, the Queen's granddaughter gave birth to Lucas, weighing 8lbs 4oz, on the bathroom floor of their home on Princess Anne's Gloucestershire estate.
Zara, the daughter of Princess Anne and Mark Phillips, has previously competed in the event but today dressed casually in jeans and a baseball cap.
She was made an MBE in the 2007 New Year Honours for her services to equestrianism and in 2012 took part in the London Olympics, winning a silver medal.
Her husband Mike Tindall, 42, revealed the news of the birth on his podcast "The Good, The Bad and The Rugby" hailing his wife as a "warrior".
Mike said: "Fortunately Zara's friend Dolly is... actually more important than I am at making sure she's been at all three of my children's births, she was there and recognised that we wouldn't have got to the hospital in time, so it was run into the gym, get a mat, get into the bathroom, towels down, brace brace brace!"
The couple's spokesperson also confirmed the baby - 22nd in line to the throne - was named Lucas Philip Tindall, in an apparent touching tribute to the late Duke of Edinburgh.
They also have two daughters, Mia, seven, and Lena, two.
In 2010, they announced their engagement and married on July 30, 2011 after meeting on England's Rugby World Cup-winning campaign in Australia in 2003.
