Proud mum Reese Witherspoon couldn't wipe the smile off her face as she walked the red carpet with her daughter Ava, 17, son Deacon 13, youngest boy Tennessee, four, and second husband Jim Toth.
The sweet group posed for a family photo before Reese's look-alike daughter Ava, whose father is Ryan Phillippe, took to red carpet to pose for some solo shots.
"She’s so much cooler than I am! She’s very cutting-edge and she knows a lot about fashion, and she has her own sense of style, which is amazing," Reese recently told US Weekly.
Ava looked elegant in a chic black dress while Reese opted for an eye-catching embellished frock.
Fans were also quick to point out how much Deacon looks like his dad Ryan!
In the 3D film, the 40-year-old lends her voice to a pig called Rosita as she participates in a singing competition to help save a theatre.
Last year, Reese admitted her kids weren't too familiar with her movies.
"They’ve never really seen me in very many films, so it should be interesting. I’m actually kind of, I have no idea what to anticipate. I know there’s going to be a lot of clips of me as a very young person. I think they’ll be a little bit stunned," she explained in October 2015 as she was being honored at the 29th American Cinematheque Awards.
Meanwhile Reese's Sing co-star Matthew McConaughey was also joined by his three kids, Levi, eight, and Livingston, three, daughter Vida, six, and wife Camila Alves on the red carpet.
