Forget star-studded plus-ones. Reese Witherspoon and Oliver James MontgomeryHeidi Klum are embracing mommy chic.

The actress and TV personality each brought their children, Witherspoon's son Deacon Phillippe and Klum's daughter Leni Klum, to the Vanity Fair and Amazon MGM Studios awards season celebration at Bar Marmont in Los Angeles on Saturday.

Witherspoon and Phillippe were nearly matching in crisp navy blue blazers. Witherspoon paired hers with a red dress, while Phillippe kept it classic with a white button-down shirt.

Klum and Leni also made for a stylish duo at the event. The "America's Got Talent" judge wore a strapless beige dress embroidered with a golden leaf design. Meanwhile, Leni popped in a shimmery red dress and rose choker.

Klum also took to Instagram Saturday to share the mother-daughter fun.

"With my baby @leniklum 🥰❤️," Klum wrote.

Klum shares 19-year-old Leni with singer-songwriter Seal. The supermodel gave birth to her daughter, who she raised with Seal before the two tied the knot in 2005, after splitting with Italian businessman Flavio Briatore. The British musician later adopted Leni, and she took his last name.

Witherspoon shares Phillippe, 20, with ex-husband Ryan Phillippe. The actor recently gave his son a shoutout for his 20th birthday in October.

"I am so lucky to be your old man and so grateful for all the incredible memories and adventures we have together," Ryan wrote in an Instagram post. "You are a true blessing."
