Jennifer Aniston and Brad Pitt call each other by nicknames in flirty exchange

Jennifer Aniston and Brad Pitt were seen calling each other by by their last names in a very flirty exchange online.

The former couple reunited onscreen for the first time since their marriage collapsed for a live read of Fast Times at Ridgemont High.

They were part of a cast of actors who took part in a digital reading of the movie’s script to raise money for charity.

Video of the event shows the cast meeting up online to start the read, with Jen, 51, and Brad’s greeting proving to be a little more flirty than expected.

They started with Brad, 56, addressing his ex-wife, saying: Hi Aniston,” and Jen replying: “Hi Pitt.”

Brad then asks: “How ya doing?” with his ex-wife replying: “I’m good honey, how you doing?”

The actor the responds: “I’m alright”.

During the exchange, they both have huge smiles on their faces while Jen is also seen twirling her hair around her finger as she chatted with her ex.

Other stars present in the included Julia Roberts, Matthew McConaughey, Henry Golding, Shia LaBeouf, and Morgan Freeman.

During the live read, Brad and Jen had to act out a saucy scene together and it didn’t seem to daunt the pair.

Brad played Brad Hamilton – originally played by Judge Reinhold – while Jen took on the part of Linda, the girl he has a crush on.

In the raunchy scene, Brad’s character head into the bathroom, while the narrator, played by Morgan Freeman says: “Brad is jerking off.”

The fictional Brad is fantasising about Linda, with Jen reading the line: “Hi Brad, you know how cute I always thought you were.

Brad and Jen were married from 2000 to 2005 and after they split, he went on to romance his Mr and Mrs Smith co-star Angelina Jolie.

The actor married Angelina in 2014 but they split in 2016 and are still going through the lengthy divorce process.
