Brad Pitt is said to be "mesmerised" by Lupita Nyong'o, and is eager to help with her career.
The two star together in 12 Years a Slave, which won the Golden Globe for Best Motion Picture - Drama and is nominated for nine Oscars.
Brad and Lupita attended the SAG awards and Producers Guild Awards together earlier this month, and Brad is said to be keen to help 30-year-old Lupita's career.
"He thinks she’s mesmerising on screen and wants to mentor her. In Angelina Jolie's absence they went as each other's dates to both ceremonies and were locked in conversation all night. They also had brunch at his LA home on the day of the SAG Awards after Brad flew in from Australia," a source revealed to British magazine Grazia.
Angelina is yet to meet Lupita, but is keen to do so with sources commenting that she's a big fan of her work.
"Angelina's desperate to meet Lupita. She thinks she's incredible. They've invited her to stay to discuss what they can work on with Brad's Plan B Entertainment company," the source remarked.
Lupita scooped the prize for Best Actress in a Supporting Role for her portrayal of Patsey in 12 Years a Slave, which prompted Brad to gift the actress with a gold Cartier watch say insiders.
"She was overwhelmed. He wants to start championing new talents and Lupita is top of his list and she's all for it - after all, this is Brad Pitt! We'll definitely be seeing them around together a lot more from now," the source added.
