The "Any Given Sunday" co-stars are teaming up again for Netflix's "Back in Action," which will mark Diaz's return to acting after an eight-year hiatus.
Barrymore said she promised Diaz to "become someone who she had been pushing me to be my whole life."
The "Charlie's Angels" star will appear alongside Jamie Foxx in the Netflix comedy "Back in Action."
"We go through real stuff with each other," Barrymore said on the inaugural episode of her daytime talk show.
The actor and husband Benji Madden announced in January 2020 that they had welcomed their first child, Raddix.
The actor participated in an Instagram fight challenge alongside Drew Barrymore, Halle Berry, Scarlett Johansson and more.
Being a mother to her baby girl is the "best, best, best part of my life," the actor said.
The "There's Something About Mary" star and her rocker husband announced the birth of their first child on Friday.
Cameron Diaz and Drew Barrymore came out to support their co-star nearly 20 years after the original movie.
Co-star Dermot Mulroney is already down.
