With Vikings returning today on Amazon Prime Video, we've taken a look at some of the biggest sibling rivalries in showbiz history, whether it be on-screen characters or real-life personalities...
1. Beyoncé and Solange Knowles
Who can forget that famous lift fight between Beyoncé and Solange Knowles in 2014 after the Met Ball? With the fight leaked online, it still hasn't been confirmed as to what it was about. Rumours spread that Jay Z had apparently planned to meet Rihanna later that night - with Solange reportedly confronting Jay Z over it. Following the fateful night, the couple embarked on a course of marriage counselling, and it looks like it worked.
2. Ryan and Rhodri Giggs
Ryan Giggs, former Manchester United footballer, is now known to the media as a bit of a love rat after his well-documented affairs. News came hot off the press in 2011 when it was reported that Ryan was having an eight-year affair with his brother Rhodri's wife, Natasha Giggs.
3. Kim and Rob Kardashian
With Hollywood's most famous reality stars in the spotlight daily, it was no surprise that the media would catch one of their feuds off camera. With Kim's wedding nuptials to Kayne being the celebrity wedding of the year in 2014, her brother was nowhere to be seen admin reports that he found their relationship "superficial bulls***!" and just a display of wealth and clothes. Whilst unconfirmed as to what the reason was, Kim and Rob came head to head prior to a pre-wedding lunch at designer Valentino's chateau - the glamour...
4. The Jonas Brothers
Known as the squeaky clean brothers of Hollywood, the Jonas Brothers shocked the world in 2011 following a disagreement on their upcoming tour, two days before it was set to kick off in Pennsylvania. Whatever the reason was, their difference of opinion saw the band splitting up and going their separate ways.
5. The Jacksons
One of the most famous families of all time, the Jacksons had a very dramatic and public family feud in 2012, following Michael's death and dispute of his will. With allegations being made on kidnapping, criminal fraud and a fight in the family home it was nothing short of a Jeremy Kyle showdown.
6. Downton Abbey's Lady Mary and Lady Edith
Downton Abbey sisters Lady Mary and Lady Edith finally came to blows in in season 6 - with Edith branding her sister a "nasty, jealous scheming b***" during a heated argument. Unfortunately for Edith, stick and stones and all, Mary was still the one that eventually found love - ouch!
7. Julia and Eric Roberts
It's no secret that Julia Roberts shares some bad blood with big brother Eric - despite once living together their relationship soured following Eric's issues with drug and alcohol abuse, along with his breakup with long-term girlfriend Kelly Cunningham. It was the final nail in the coffin when Julia sided with Kelly and helped fund her legal defence to gain custody of Erin's daughter. Good news though, looks like all has been forgiven, with the siblings reuniting following their mother's death.
8. Liam and Noel Gallagher
Known for their long standing feud after the pair famously fell out in 2009, Noel reported that he felt bullied during his time with Oasis - and the band split shortly after. The brothers weren't afraid to share their feelings with the media, with Noel describing Liam to Q Magazine as "rude, arrogant, intimidating and lazy," further adding: "he's the angriest man you'll ever meet".
9. Gary and Wayne Lineker
With their rift dating back to 2008 - this is a feud which looks like it will never be fixed. When football pundit Gary Lineker divorced his first wife Michelle, he moved on quickly to lingerie model Danielle Bux. Jetting Danielle off to Ibiza to meet brother Wayne, it was during this trip when the fall out happened. Without knowing the exact details, Wayne has told the press that Danielle is the reason for their rift, and they have since not spoken.
10. Vikings' Ragnar and Rollo
In the season three finale of Vikings, we saw Ragnar (Travis Fimmel) and his fellow warriors sail from Paris back to Kattegar with their treasure, with brother Rollo (Clive Standen) staying behind to safeguard their interests. But Rollo has made a deal with Emperor Charles to turn against his people in exchange for land and his daughter Gisla's hand in marriage.
