In this week's A-List Insider: a Black Friday album clash between Rihanna and Chris Brown, Beyoncé is accused of going under the knife and Hunger Games' final instalment disappoints at the box office.

Chris Brown pushes album date back

This year's Black Friday just got the 'ex' factor thanks to former love birds Chris Brown and Rihanna. The Liquor singer will take pre-orders for new album Royalty on Black Friday, the same day Rihanna is expected to stream her new album Anti on Tidal for a week.

Royalty was originally planned to be released the same day as Anti – 27 November – but the LP has now been pushed back to 18 December. This means Brown's fans will have to wait an additional 21 days to hear his new material, the follow-up to 2014's X.

Beyoncé accused of having botox

Elsewhere in the world of music, Kevin Federline – also known as Britney Spears ex-husband – has accused Beyoncé of having botox and ruining her face with cosmetic surgery.

It all went down on social media after celebrity blog Terez Owen posted a snap of Queen B with her hubby Jay Z ringside at the Canelo Alvarez vs Miguel Cotto boxing match in Las Vegas over the weekend.

The popular sports media blog tweeted an article about the 34-year-old diva showing off some serious cleavage in a plunging black dress, and Federline responded with the tweet "She looked botoxed".

Just in case fans didn't get the insult the first time, he followed up his message with a comment that read: "So sad when a beautiful woman chops and screws her face up with botox and surgery. #sawface".

Fans were understandably shocked by the random outburst and jumped to her defence. Let me put it this way. Federline is probably somewhere wishing he had never messed with Queen B.

Final Hunger Games film disappoints at the box office

And finally, The Hunger Games: Mockingjay - Part 2 has opened with the lowest US box-office takings of the entire franchise. Although it was thought that fans would be heading to the cinemas in their droves to see how it all ends for Katniss Everdeen, that wasn't the case. The lacklustre performance saw the film make an estimated $101m (£66m). In contrast, Catching Fire raked in $158m in its first weekend.

On a brighter note it still managed to top Spectre, which is Daniel Craig's latest outing as James Bond, to become the fifth-highest opening of 2015 (behind Minions, Furious 7, Avengers: Age Of Ultron and Jurassic World).
