WARNING: This article contains spoilers from The Bear.

The Bear season four has debuted, finally introducing the blunt Francine who has only been spoken about for the past three series.

Carmy Berzatto (played by Jeremy Allen White) and the team are back with all 10 episodes of season four coming out on Hulu in the US and Disney+ in the UK this week.

During the first three seasons, Neil Fak's (played by Matty Matheson) sister Francine "Francie" Fak has been talked about in relation to a ginormous feud she had with Natalie "Sugar" Berzatto (Abby Elliott).

While she hasn't been physically present in the restaurant drama, her presence has been felt in family conversations about her and Sugar's past conflicts.

But it was in season four's sixth episode that fans finally got to put a face to the name and even more excitingly, it was a famous face at that.

Episode six saw everyone gather for the wedding of Tiffany (Gillian Jacobs) and Frank (Josh Hartnett) and among the guests was the elusive Francine Fak, portrayed by none other than actress Brie Larson.

The 35-year-old is best known for starring in some unforgettable films including 13 Going on 30, Captain Marvel, 21 Jump Street and Kong: Skull Island.

It was in 2016 that Larson won her first Academy Award for Best Actress in the thriller Room which sees her character Joy and her son held captive in a shed for years.

Fans were overjoyed to see Larson join The Bear as Brie, taking to X to share their thoughts.

Someone happily wrote: "Brie is killing it! This show always surprises me with their cameos ."

Another commented: "She´s so unreal! Brie Larson in The Bear", while a third remarked: "Can someone finally please let Brie Larson star in a f*****g comedy now?"

Her appearance wasn't without its fireworks as Francine and Sugar were at loggerheads once again at the wedding.

Even though the reason for their rivalry wasn't revealed entirely, there was a hint at what it could have been about.

One of the cousins jokingly shared that the feud could have begun because they hooked up with neither of them confirming this information.

Peter (Chris Witaske) asked Sugar if she was in love with Francine, to which she paused before blowing raspberries and denying the claim but could there be any truth in it?

The Bear is available to watch on Hulu in the US and Disney+ in the UK.
