Model Kelly Brook is engaged to former `Gladiators` star David McIntosh.

Kelly has been dating David, who is also known as Tornado, for just 11 weeks and the two even split briefly during that time. Kelly, 34, was left 'dumbstruck' by David's proposal but took just three seconds to agree, reports dailymail.co.uk.

A friend of the model, told The Sun: `It's still a closely guarded secret and came to Kelly as a massive shock.

`But she is at that time in her life now where she wants to make a commitment and she has fallen head over heels for David.`

It's thought that the former Royal Marine popped the question while the couple were planning a romantic trip to Dubai.
