Queen Bey's 45-year-old husband of eight years resembled guitar god Jimi Hendrix as he puffed on a suspicious-looking cigarette alongside Usher's second wife Grace.

The 37-year-old R&B crooner rocked a similar afro wig and open-chested bead bling as the 21-time Grammy winner.

Meanwhile, 35-year-old Alicia and her husband of five years, Swizz Beatz, looked straight out of HBO's The Get Down in their retro costumes.  

Weee! The pop diva had no problem partying through the 'doctor-ordered vocal rest,' which led to the postponement of her concert this Wednesday

Upgrade your denim in Alicia's flare jeans by Frame

Beyonce's 35th birthday party was a 70's inspired extravaganza that drew the likes of Kelly Rowland, Jourdan Dunn and Solange Knowles.

Alicia Keys and her husband Swizz Beatz were also invited guests and the Girl On Fire singer dressed according to the theme in a shredded t-shirt, wide headband and platforms. Groovy!

Her jeans exuded 70's vibes with their high-waisted silhouette and fabulous flared bottoms. They're by Frame Denim and although this exact wash is sold out, Farfetch has them in a lighter hue so click right to snap them up now.

If you've missed the boat size-wise then do not fear, because there are also a few other cool flared pairs ready for the taking all lined up in the carousel.

Team with platform heels or flatform sneakers and you'll be looking old-school cool this season.
