Jason Sudeikis Reveals His Unique Valentine's Day Plans for Olivia Wilde

The actor also opens up about their 9-month-old son, Otis.

Well, kind of.

"I don't know what to get. I feel like everyday is Valentine's Day in our relationship," he added. "I'll give her the gift of gab. ... I'm gonna really answer when she says how was my day. I'm gonna give a real thoughtful answer!"

Sudeikis, 39, and Wilde, 30, have been engaged for more than two years. Their son, Otis, was born last April, and since then has been showered with love from his parents and his two aunts, who live nearby.

"He smiles a lot. I would say that any looks that he's got going -- I feel like he's a real cute little guy -- that's Liv's doing, and then him smiling I feel like is both of us," he said. "He's surrounded by love 24/7 and 80 percent of it is female-based, so I think he'll turn into a really good guy. I'm excited to see who he is."
