And while some A-listers were content to rock one, or maybe two, fashion and beauty trends, leave it to JLo to completely own three!
Jen had a pretty great week last week, as the last season of American Idol kicked off, and her new crime drama, Shades Of Blue debuted in the US on Thursday (7 January) along with great praise and staggering viewing figures.
So, how fitting that the Latino queen rounded it all off with a winning, triple-whammy on the Golden Globes red carpet?
Trend number one was her gown.
Colour was big news on Sunday night and while many stars chose jewel tones and hot red shades, Jen opted for a stunning yellow, Giambattista Valli number which she described to E!'s Ryan Seacrest as:
"Mustardy... yellow... marigold."
We couldn't have put it better ourselves, Jen!
JLo teamed her gorgeous, floor-length gown with deep, berry lips (another HUGE trend of the night with Rooney Mara and Laverne Cox also getting in on the dark pout action) and a loose, shoulder-length lob that we also noticed the gorgeous Kate Hudson wearing.
Dress, hair, make-up. Nailed it.
