No matter how famous you get or how much money you make, nothing ever beats a night out with mom, as these stars proved at past Oscar ceremonies.
With Hollywood's biggest night just two days away, ET is looking back at some of the most adorable moms to ever grace the Academy Awards red carpet.
The Revenant star loves bringing his German-born mother, Irmelin Indenbirken, to the Oscars. When DiCaprio finally took home his first Oscar last year after five previous nominations, Indenbirken was on cloud nine.
"I'm so happy you have no idea," she told ET. "He's very, very happy. He's thrilled."
The Great Wall star was still new to Hollywood in 1998 when he walked the red carpet with his mom Nancy Carlsson-Paige.
Like Damon, Affleck also had his mom, Christine Boldt, at the 1998 event to congratulate him after winning the Oscar for Best Original Screenplay for Good Will Hunting.
When McConaughey won the Best Actor Oscar for Dallas Buyers Club in 2014, he made sure to thank his mom Mary McCabe in his acceptance speech.
"To my mother, who's here tonight," he said. "Who taught me and my two older brothers, demanded that we respect ourselves, and what we in turn learned was then we were able to better respect others. Thank you for that, mama."
Gosling brought his mom Donna and his sister Mandi for support when he was nominated for Best Actor in 2007 for Half Nelson.
Cooper's mom, Gloria Campano, was head over heels to accompany her son to the Oscars in 2013, but she didn't let it get to her head. Campano was so humble about the occasion that she didn't even get a new dress.
"I just pulled it out of my closet," she confessed to ET. "I didn't really go crazy."
The 89th Academy Awards, hosted by Jimmy Kimmel, air live Sunday at 5:30 p.m. PT/8:30 p.m. PT on ABC.
