We know what you're thinking: another week, and yet another red carpet event. This week's soirée, the Billboard Music Awards held at the MGM Grand Garden Arena in Las Vegas, saw our favourite celebrities working the carpet with some flawless looks, and we can't pass up taking our pick of the best. What stood out this time were the lips, and here's our two cents worth on the best kissers that graced the event, and how to re-create them:

Rita Ora

Red lips will probably never, ever go out of style. Christina Aguilera, Taylor Swift, Gwen Stefani...the list of celebrities that make it their signature look rolls on. But Rita Ora's perfectly penciled in matte, red lips are the go-to example on how to do the classic colour well.  Try a cream or satin finish if matte is too stark for you.

Iggy Azalea

While we are on the fence regarding the matter of matching lip and hair colours, Iggy Azalea does sport a covetable posey pink lip that is great for fair skin tones and will take you from day to night.

Zendaya Coleman

Picking the wrong shade of nude tends to visually drain colour from your face — you end up looking under the weather when you are really not. Zendaya Coleman schools us on getting the nude lip down by going for a shade that is slightly darker than her skin tone, with blush undertones to retain a touch of colour.
