Nick Knowles and Idris Elba were among the stars who enjoyed a boozy afternoon while celebrating the fourth and final day of the Cheltenham Festival on Friday.
DIY SOS star Nick, 60, looked suave in a three piece Ralph Lauren suit as he stepped out alongside his tartan-clad girlfriend Katie Dadzie, 32, who was dressed in a Holland And Cooper ensemble and Gucci tights.
And it appeared Nick had the luck of the Irish on St Patrick’s Day as he was pictured punching the air while celebrating a win with Katie and Kirsty Gallacher – sipping on a refreshing beverage as he watched out to the course.
Elsewhere, actor Idris was all smiles while he sipped on a dram at the event, with fellow screen star Luke Evans laughing with an alcoholic beverage of his own.
Despite the Gloucestershire racecourse relaxing its strict dress code for the first time in its 200 year history, the celebrities made sure they dressed to impress before saying cheers to the end of the four-day event.

The historic society event, which dates back to the early 19th century, has unveiled a new ‘inclusive’ dress code this year, which organisers hope will make spectators feel ‘confident and at-ease’ for their visit.
This means dresses, heels and hats are no longer mandatory, as organisers hope to attract a younger crowd to the venue, welcoming jeans and trainers.
In the past, entry into some enclosures has required the wearing a jacket and tie while wearing trainers has also been frowned upon.
Racegoers are free to wear what they want at the Jockey Club’s 15 racecourses in a bid to make horseracing more ‘accessible and inclusive’.
Instead of restricting racegoers from watching the action in certain enclosures based on what they are wearing, the Jockey Club has told its customers to ‘dress as you feel most comfortable and confident’.
The only exceptions to the new policy at any of the 342 fixtures staged by The Jockey Club is offensive fancy dress or offensive clothing of any kind and replica sports shirts.

The announcement comes at a time when racecourse are battling to stem a fall in attendances.
Nevin Truesdale, Chief Executive at The Jockey Club, said last month: ‘Horseracing has always been a sport enjoyed by people from all different backgrounds and it’s really important to us to be accessible and inclusive.
‘We hope that by no longer placing an expectation upon people of what they should and shouldn’t wear we can help highlight that racing really is for everyone.
‘For those who visit our venues, a day at the races is all about spending quality leisure time with friends and family and we believe people enjoy themselves best when they feel relaxed. A major part of that is wearing clothing which you are comfortable in.

‘While The Jockey Club has a rich heritage and history it is also a forward-thinking organisation which places a great emphasis on diversity and inclusion and always seeks to reflect modern trends.
‘So, when we reviewed this area of the raceday experience, it has been clear to us that enforcing a dress code seems rather outdated in the 21st Century in the eyes of many of our racegoers.
‘Of course that doesn’t mean we are discouraging people from dressing up for a day at the races if they want to.’
‘This is about giving people a choice and the opportunity to come racing dressed however they feel most comfortable and confident, while also bearing in mind the challenges regularly presented by the British weather.’
