How to be Katie Holmes:

She rose from forgettable Dawson’s Creek alumnus and C-List actress to become Mrs Tom Cruise-to-be and hot Hollywood property -- all in the space of three months. We look at how Katie got there.

1. Profess a crush on one of today’s biggest earning stars and reveal there was a poster of him on the bedroom wall.

2. Forget all Catechism class teachings and start getting serious about Scientology, a religion based on the teachings of a science fiction writer.

3. Carry out a complete wardrobe overhaul. Ditch proper dresses and the jeans-cardigan-sensible shoes look for sexy dresses and superstar extra-large shades.

4. Be willingly whisked away to Rome for a romantic téte a téte, and have 40 Armani dresses plonked down for picking to attend a glitzy awards show on the same night. Bummer!

5. Develop a sudden affinity for lots of camera lenses and popping flashbulbs in the face. Not to mention possible blindness.

6. Smile gracefully and mouth “I love you” on a TV talk show when boyfriend goes completely berserk and jumps on a couch, yelling that he loves you.

7. Patiently dismiss all accusations that the romance is a publicity stunt. So what if both your movies don’t turn out to be summer blockbusters after all the money it took to make them?

8. Kiss your man so much -- and so often -- that unsightly cold sores break out like a rash.

9. Continuously bend over slightly or tilt the head at awkward angles to kiss/ pose for pictures/ laugh at jokes/ maintain tender gazes with your man. Realise this could go on until your hair is white and you have three teeth left but happily accept that fate.

10. Be dragged to the top of the Eiffel Tower at 1am and have a massive honker of a diamond ring slid onto the all-important fourth finger of the left hand.
