“Brad did too. Her friends are all very generous and creative, and she seemed very excited by all the gifts.”
The insider added that Jen and Brad have put all the bitterness of their divorce behind them and they now get on well.
They explained: “Whatever caused their divorce is long in the past.
“Brad and Jen have a very civil relationship.”
Jennifer turned 50 this week, two days after her big party at the Sunset Tower in West Hollywood.
The bash was packed with famous faces including Reese Witherspoon, who was pictured looking worse for wear as she fell down a flight of stairs on her way out.
Other guests included Gwyneth Paltrow, Katy Perry, George and Amal Clooney, Ellen DeGeneres, Kate Hudson and Demi Moore.
However, the biggest surprise was Brad turning up to party with his ex-wife – who he famously left for Angelina Jolie.
The pair were married from 2000 until 2005 and Brad went on to tie the knot with his Mr and Mrs Smith co-star Angelina, before divorcing her too.
After her doomed marriage to Brad, Jen tied the knot again in 2015 when she wed Justin Theroux.
However, that didn’t last either and they split in 2017. The former couple’s divorce is expected to be finalised this year.
They also appeared to have stayed on good terms after the break-up as he sent her a sweet happy birthday message via Instagram .
