The 'Booty' singer, 45, showed off her incredible figure in a cut-out nude gown as she sauntered down the red carpet, before preparing to perform at the ceremony alongside Iggy Azalea.
But the songstress didn't just nail things on the fashion front - she got things SO right in the beauty department too!
Jennifer decorated her brown peepers with heaps of smoky charcoal grey eyeshadow teamed with bold, arched brows, a flush of peach on her cheeks, plus a slick of her fave nude lipgloss.
And her highlighted mane looked totally incredible styled in a super-voluminous, bouncy blow-dry, with the front section swept back away from her face for heaps of drama.
To recreate her fierce hairdo at home, just follow these easy steps...
1. First up, wash and condition your hair with volumising products (like Mark Hill Love Big Hair! Big It Up Volume Shampoo, £5.49, and Conditioner, £5.49) before towel drying (remember to gently pat your hair with the towel - never rub as this can damage your strands and prevent the cuticle from lying flat).
Next, apply a heat protecting product. Our fave is L'Oréal Professionnel Mythic Oil Seve Protectrice, £13.59 - not only does it protect against 230°C heat, it also leaves our tresses feeling silky smooth.
2. Tilt your hair upside down and rough dry until it's slightly damp. Flip your hair back up and section off the top half of your hair, just leaving the bottom layer. Blow-dry this layer with a round brush, curving your brush inwards towards your back.
3. Continue blow-drying sections of hair, working your way up from the bottom layers to the top. When you get to the very front section of your hair, make sure you don't create a parting, and instead blow-dry the hair backwards.
4. The key to making this look last? A hefty helping of hairspray! Go for a long-wearing formula, like L'Oréal Paris Elnett Satin Hairspray Lumière Supreme Hold, £6.60, and apply sparingly to start with, gradually adding more as you go (but not too much - you don't want your barnet to go crispy!). Keep combing your hair backwards as you spray to ensure it stays in place.
