Black Friday 2015: Nicki Minaj, Chris Brown, Ryan Seacrest and other stars promote deals and sales

With just days left until the shopping frenzy that is Black Friday, hundreds of retailers are promising blockbuster savings on everything from fashion to tech, jewellery and short breaks. While big name brands will be doing their best to attract consumers come 27 November, stars including rapper Nicki Minaj are getting in on the action with some promoting of their own.

The Anaconda hit maker has announced she will unveil her K-Mart collection on the biggest shopping day of the year. Taking to Instagram, she previewed two black figure-hugging looks from the range with the caption: "I'll unveil the rest of my limited capsule collection on a new website this Black [PINK] Friday. Hair by Kim Kimble. Make up by Sheika Daly. #TheNickiMinajCollection for KMart. by @grizzleemusic"

Meanwhile, country music legend Dolly Parton comes bearing gifts for her fans after announcing a 20% markdown on all merchandise purchased on her website. The 69-year-old, who performed at Glastonbury in 2014, is selling everything from mugs to T-shirts emblazoned with her face.

Media mogul and radio personality Ryan Seacrest did his bit to promote Macy's Thanksgiving Parade and Black Friday sales with a not-so-subtle tweet that read: "It's almost thanksgiving which means it's almost black friday which means it's definitely time for @macys epic ad."

On the music front, former lovebirds Rihanna and Chris Brown will be dropping their respective albums Anti and Royalty on Black Friday. While fans can get their hands on Royalty when it is released worldwide, Rihanna's eighth studio album will be exclusive to Jay Z's music streaming service, Tidal, until 4 December.

Meanwhile, the post-Thanksgiving US tradition is continuing to make its mark in the UK. Tesco, Currys and John Lewis, as well as online retailers such as Amazon and eBay, will be offering bargain prices and have also altered their trading hours and bulked up staff in a bid to prevent the chaos of 2014's event.
