Ben Affleck's Argo won Best Picture at last year's Oscars, but he was a no-show at Sunday's ceremony.
Instead, his wife Jennifer Garner flew solo at the 86th Annual Academy Awards. The Dallas Buyers Club star modeled her custom Oscar de la Renta dress on the red carpet and chatted with E! News about her son Samuel's adorable reaction to the fun and flirty frock. "He made it just for me and I love it," the 41-year-old movie star told Ryan Seacrest of de la Renta's bespoke design. "When my 2-year-old saw me in it, he said, 'Mama, you look so pretty!' So I said, 'Okay, that's the one. There you go!'"
Garner was on hand to support her costars Jared Leto and Matthew McConaughey, who took home the Best Supporting Actor and Best Actor awards for their roles in the critically acclaimed drama.
Because their characters both had AIDS, Leto and McConaughey each dieted like crazy to lose weight.
According to Garner, however, their constant hungriness didn't ruin the mood on set. "I think there should have been more crankiness than there was. I have yet to see Matthew McConaughey cranky. I've done two movies with him [2009's Ghosts of Girlfriends Past and 2013's Dallas Buyers Club]. He is steady as a rock," she said of the actor, who triumphed over fellow nominee Leonardo DiCaprio. "But if it had been me, I would have been so cranky. I was cranky when my snacks didn't show up on time!"
Garner had no reason to be cranky after the Oscars: Affleck joined her at Vanity Fair's party. The couple, who tied the knot in 2005, mingled with Glenn Close, Chris Hemsworth and Liam Hemsworth.
