Well, it’s pretty impossible to call.
Both girls look absolutely ah-mazing as they celebrated the launch of Samsung’s new Galaxy S6 with Chrissy’s husband John Legend last night.
Model Chrissy, 29, was wearing a pair of *very* saucy hot pants, which she paired with thigh-high boots, a black vest and a dark blazer.
She kept her accessories simple and sported smoky eyes and a tousled ‘do.
Chrissy was clearly pleased with her look. She shared an Instagram picture of herself planting a smooch on make-up artist Beau Nelson’s cheek, saying: ‘Thank you my @beau_nelson and @clarisshair!’
Emily, 23 – who leapt to fame in Robin Thicke’s Blurred Lines video – decided to show off a different part of her body, working a cut-out boob tube with orange trousers.
She’d blow-dried her brunette locks into a low-key backcombed style.
Chrissy and Emily both showed off their sexy ensembles on Instagram, posting photos of themselves together on a sofa with John, 36.
In Chrissy’s image, John had wrapped his arms around her and Emily as she draped herself over her hubby. Emily’s version saw them both cuddling up to the singer.
‘Spending the night at the @samsungmobileUSA studio with @emrata celebrating the #GalaxyS6!’ Chrissy captioned her shot.
Emily said: ‘Tonight with these sexy people @chrissyteigen @johnlegend at the @samsungmobileusa #galaxylife.’
It seems Chrissy and Emily have become close – we couldn’t help noticing that the pair were holding hands in the snaps.
In fact, Chrissy seems to be a popular gal in the world of showbiz.
