They are rarely seen out together and never make public appearances on the red carpet like so many other celebrity couples.

So Katherine Jenkins and fiancé Gethin Jones caused quite a stir as they arrived at Wimbledon today to watch Jo-Wilfried Tsonga take on Novak Djokovic in the men's semi-finals.

Opera star Katherine looked stunning in her £275 Whistles Siri dress which she teamed with tan accessories.

And former Blue Peter presenter Gethin also looked smart in his beige blazer, black trousers, shirt and tie as the pair made their way to their seats to watch the match.

Before arriving at the All England Club to see the first game, and Andy Murray's match against Rafael Nadal later in the day, Katherine tweeted: 'It's Men's Semi Final day at Wimbledon and I'm in the Royal Box! Come on Murray!'

Katherine and Gethin announced their engagement in February this year after Gethin popped the question with a £10,000 ring.

A source close to the couple told The Mail on Sunday at the time: ‘Gethin proposed last month, it was a wonderful start to the year for both of them.

'Katherine is so happy and can’t wait to start planning her wedding which will be next year.'

And Gethin hinted earlier this year that the couple's nuptials are set to take place in Wales.

Asked if they had chosen a venue, Gethin replied: 'We haven’t got that far yet, but we are both Welsh. I can tell you we are looking at some time next year.'

He later added: 'All of these details are between me and her. It is natural that people like to know what is happening, but we try and keep our relationship private.

'We are simply together because we like each other.'

Smiles all round: Pippa Middleton was also in attendance, showing off her toned arms in a sleeveless dress

The notoriously private pair have already decided that there will be no tacky wedding magazine deal on their big day.

Last summer they moved into a £4.7 million house in Richmond, South-West London, prompting rumours that they were thinking about getting wed.

Asked whether she wanted children in a recent interview, the singer said: ‘Oh definitely, one day. I can see myself married with children. I want to be a really good mum. Ultimately I would want to be able to combine both a family life and my singing career.’

The couple met in 2007 when Gethin was a contestant on Strictly Come Dancing and Katherine made a guest appearance on the show.
He has said of their relationship: ‘It’s good and if I wasn’t happy, you would know it.’
Other stars at Wimbledon today included Pippa Middleton, Michael Parkinson and Denise Lewis, as well as royals Princess Beatrice, Princess Michael of Kent and Prince Andrew.
