"I reckon Cherie Blair might have a bit of a crush on David Beckham. Why? Well her body is leaning towards him - particularly her head. Our intimate personal zones are about arms' length away - Cherie is just on the outside of David's intimate zone and managing to lean in. And look at her facial expression - she's like a nervous schoolgirl with a boy she fancies.

Becks, on the other hand is keeping himself very under control. His hands are protectively covering his groin - men do this as an unconscious reaction when they feel slightly threatened. The are literally protecting the crown jewels. Players do the same thing on the field when a free kick is being taken. An unrequited crush I think."

"Natasha Kaplinsky is turning on the charm here with her flirty dancing. Notice how her head is cocked to one side, which we do to show interest. Natasha is clear taken by her Strictly Come Dacning partner Brendan Cole. He, on the other hand, is trying to be very professional - his back is straight and his upper body is leaning slightly back. Check out his arms placed professionally in the small of Natasha's back, a low flirt zone. Also his hips are pushed slightly away from her - when a bloke likes you he unconsciously puts his best bits forward . . . literally. This looks very much like a one way flirting session - her towards him."

And not convinced that is was strictly dancing, Cole was dumped by his financee Camilla Dallerup.

"Tara has said, 'I can really flirt with people I don't fancy but the man I do fancy I can hardly look in the eye.' This holds true for in her body language - she is clearly feeling a bit nervous sitting on the lap of Duncan from Blue. See how her body is leaning away from him - if she was comfortable she would be leaning closer. Her hand is on his leg but it's down towards his knee. If she really was flirting she would be unconsciously moving her hand closer towards his naughty bits. Poor old Tara suffers from the classic problem of many of my female clients - she puts on the green light (come and get me) to people she doesn't fancy and puts on a red light (go away I'm nervous) to people she does fancy."

However, Tara has always insisted she and Duncan are just friends. She is currently dating Matalan heir Jamie Hargreaves.

"Hello! There is some serious action going on here. Jame Hewitt is clearly taken by Diana and is turning on the charm. Notice how his whole body is facing directly towards her and his upper body is leaning forward - our bodies move towards people we like. His slight smile and his very direct eye contact all adds to to a big flashing 'How are you hottie' sign. And check out Diana, she is feeling it and feeling shy - leaning away and looking away from his intense flirty eye contact. Althought she's holding that huge polo trophy which creates a barrier beteen them, in a tell-tale sign she's pushing her hips towards him where they want to go. No wonder these two got together. What a charmer!"

But of late Hewitt's gone from blue blood to blue TV he had a fling with glamour model Jodie Marsh and joined her on Television X The Fantasy Channel.

The Little Britain star has proved a big hit with the lay-deez.

Walliams - who could never be described as classically good looking - has been linked with Czech model Petra Coulson, Denise Van Outen, Lisa Snowdon, Patsy Kensit and Abi Titmuss. Recent research has shown women prefer men who 'produce humour' and as a result Walliams has earned a reputation as a comic Don Juan.

"To be a really good flirt you have to make the person you are seducing feel special, the centre of attention. His attention is everywhere else but on her. Also the more attention you pay to your sorroundings, the more interested you are in being on the pull. Notice how he is looking around and away from Lisa - literally looking out for something or someone else. A good laugh but no future here."

"This photo was taken three months after the fellow Swedes were first introduced at a party. Their affair was soon to become public. Here, their fear of getting caught is evident. Ulrika is trying to look as if she's interested in what the speaker is saying but she's subtley eyeing up Sven out of the corner of her eye. Serial flirt Sven is looking directly at the object of his desire. If there was nothing going on, they would be relaxed, listening and happy to look in each other's direction."

Two years later, 56 year old Sven was at it again, allegedly 'flirting' with Faria Alam, an FA secretary. She claimed Sven rubbed his leg against her at a dinner, then took her on a date, telling her: "I have always liked you, the way you dress, the way you are. You are very beautiful. When a man wants something he goes and gets it and I want you."
