Nick Knowles, 61, and his fiancée Katie Dadzie, 33, hold hands as they arrive at star-studded day three of Cheltenham Festival

Nick Knowles and his fiancée Katie Dadzie walked hand-in-hand as they attended day three of Cheltenham Festival on Thursday. 

The DIY SOS presenter, 61, who proposed to Katie, 33, in New Orleans in July, looked happier than ever with his wife-to-be. 

She put on a stylish display in a burgundy wool coat with gold buttons, that she teamed with a pair of heeled boots from Holland Cooper. 

Katie styled her look with a green patterned silk scarf and a matching leather handbag, before pinning her hair back with a black bow.

Nick opted for a smart navy blue suit with a white shirt, colourful tie and a brown wax jacket layered over the top. 

Joining the couple at the hotly-anticipated event was Georgia Toffolo, 29, who put her best fashion foot forward in a suede coat by Fairfax & Favor. 

The TV personality added a high-neck jumper and a bright red satin skirt underneath with a matching headband.  

James Nesbitt was also in attendance, wearing a checkered coat with a navy blue sweater and trousers. 

Elsewhere, Josie Gibson and Sam Thompson were seen fooling around as they attended day three of Cheltenham Festival. 

The former I'm A Celebrity campmates have reunited to report on the races for ITV's This Morning. 

Arriving at the racecourse, Sam, 31, wore a fun jockey hat, complete with googles and a whip as he posed for photos with his co-star, 39. 

Josie could barely contain her laughter as the radio presenter got into character and pretended to ride an imaginary horse. 

Putting on a stylish display, she opted for a long khaki coat with a white blouse and knee high suede boots by Holland Cooper. 

Josie topped off her look with a fedora hat from Hicks and Brown and a silk scarf, styling her hair into glamorous curls. 

Meanwhile, Sam wore a blue suit with a white shirt, navy tie and brown suede shoes for the event. 

Cheltenham Festival punters faced 'absolute bedlam' when trying to leave the racecourse when heavy rain created traffic chaos on the event's opening day.

Torrential downpours and boggy fields caused a nightmare in the festival car parks, as thousands tried to head home at the end of a thrilling day of racing.

Vehicles got stuck in the heavy mud, creating queues of up to two hours on the opening day of the four-day event. 

Those arriving to watch today's racing are also likely to encounter travel problems, as images from this morning have shown tractors pulling trapped cars out of the thick mud after more heavy showers fell overnight. 

More than 60,000 supporters attended the opening day of the prestigious 164-year-old racing meet and swarmed the course's grandstand, betting rings and Guinness Village.

Rain was expected to fall throughout this week, but last night's downpours were significantly heavier than what was forecast, leading to today's Glenfarclas Cross-County Chase being postponed.

The race is run on a different track to other races at the festival and does not drain as well.

The track had expected 2-4mm of rain overnight but 6mm has already fallen - and another 6mm is forecast on the way.

A Cheltenham spokesperson said: "Following 11mm of rainfall throughout yesterday, there has been no improvement in the conditions on the Cross Country Course and with areas of the track unraceable, the Cross Country Chase has sadly been abandoned.

"The forecast for the remainder of the week continues to look unsettled, with further showers likely on both Thursday and Friday.

"There will therefore be insufficient improvement to the Cross Country Course by Friday, and the decision has been taken not to reschedule the race."
