The gorgeous American Idol judge looked nowhere near her 44 years of age as she wowed the paparazzi and bossed the blue (!) carpet at the Hollywood party and if anyone can get away with glitter in January, J.Lo can!
Even if it was only on her nails...
Jennifer is lucky enough to have nail-man-of-the-moment, Tom Bachik as her go-to manicurist (he did Zooey Deschanel's cute daisy nails at last weekend's Golden Globes, btw), so frankly we expect nothing less than nail perfection whenever we see her at A-list events.
But we have to admit, glitter is much more of a festive, pre-Christmas look, than a January, post-parties trend.
In our worlds, anyway!
We suppose if you're one of Hollywood's hottest singers/actresses/presenters, however, your world is full of sparkle any time of the year!
So, if you fancy defying the cold and glitzing up your January, we can't think of a cheaper and easier way than with a glittery gold manicure.
To recreate Jennifer's look, we're totally in love with Elegant Touch Glitter Twinkle Twinkle Press-On Nails, £7.10, eleganttouch.com as you basically just stick them over your natural nails and go.
You could also try painting your nails with your favourite gold polish, then sprinkling gold glitter on top. It's a little more fussy, but much more fun!
