I'm in shock! Rhys and Sienna on the rocks? Tell me it's not so.

Agreed, they were never the most conventional of pairings - she's drop-dead gorgeous while he's more character actor than leading man - but as the relationship blossomed there was clearly had something very special about the lanky lad from Wales.

And Sienna's not the only one to eschew matinee star looks when it comes to love. Christina Aguilera and her music exec husband, for example. The ultimate glamour puss found romance with someone who looks a lovely chap, but isn't exactly your typical heart-throb. Ditto gorgeous Isla Fisher and that quirky Borat fellow. And remember Julia Roberts falling for country music star Lyle Lovett? She was so impressed by the rugged-face singer she ended up married to him - though the relationship did end in divorce.

So before you jump on the 'I told you so' bandwagon when it comes to Rhys and my favourite London party girl, hang fire. Wedding bells may not be out of the question after all.
