And what caught our attention as JLaw celebrated the third and penultimate movie in the series was her clever hairstyle.
Why? Because if you remember rightly, JLaw has a short bob, yet she's STILL managed to work it into a fabulous little updo. Er, pass us her hairdresser's phone number – like now!
Held at The Odeon Leicester Square in London, last night's movie premiere welcomed the likes of TOWIE stars Jessica Wright and Samantha Faiers as well as Alexandra Burke, Katie Price and Hollyoaks actress Gemma Merna who looked fabulous with her new darker hair.
The stars of the Hunger Games movies were also out in full force, but Jen definitely led the way in the glamour stakes in an embellished monochrome Dior dress, strappy black sandals and soft, barely-there make-up.
What we didn't expect to see, however, was her short, bobbed hair scooped back into such a cute, sexy updo.
Jen had her hair cut into a super-short, pixie crop about a year ago, and has more recently been wearing it slightly longer in a jaw-length, wavy bob.
To be honest, we'd have been more than happy to see JLaw wear her hair loose and sleek, or slightly finger-waved for a bit of extra glamour at last night's red carpet affair. But we're loving how she's gone that extra mile with her locks and totally nailed the 'short hair updo'.
Whoever reckons shorter hair is less versatile than long locks couldn't be more wrong!
If you have a bob and fancy recreating Jen's look (those Christmas parties are just around the corner after all), here's how...
1. First, apply mousse to wet hair, then rough-dry it with your hairdryer, using your fingers to lift the roots as you dry.
2. Next, starting from the top layers, gently backcomb your hair in sections, working all the way down the back of your head until you reach the bottom layers.
3. Loosely pin small sections of your hair as far down the back of your head as your hair allows, ensuring you don't pull your hair back too tightly as this will destroy all that hard, backcombing work! And if some of your ends stick up, try tucking them under and adding extra grips.
4. Pop on a black, alice band like the Scunci Comfort Grip Headband, £2.45 for two, superdrug.com. Place it gently on your head, pushing it back to hold your fringe off your face, but not so much that it flattens your hair – volume is good, remember?
5. To finish, keep it red-carpet secure with a good spritzing of hairspray and you're good to go.
