Jason Sudeikis has no sense of smell

Olivia Wilde says Jason Sudeikis "has no sense of smell."

The 'Lazarus Effect' actress, who has 10-month-old son Otis with the 'Horrible Bosses' actor, claims her fiancé, 39, thinks she is a great cook because he is unable to taste food properly.

She said: "I like to cook, but I also have the easiest audience in the world. My fiancé has no sense of smell - he was born without it - so he thinks everything I cook tastes amazing. It really builds my confidence."

While Jason is completely lacking one of the six senses, the 30-year-old actress admits her eyesight is getting worse as she gets older.

She told PEOPLE magazine: "Jason got me a huge Scrabble board for Christmas that's on a lazy Susan. All the pieces are huge, and now that I'm an old person, that really helps my elderly eyesight."

The brunette beauty also claims she is becoming increasingly forgetful.

She said: "I've had mommy brain since I was like 15. I don't understand how everyone keeps their two gloves that match each other or their keys and wallet. I don't understand it."

The 'Drinking Buddies' star says her life has changed a lot since she gave birth to her son.

Asked when she saw her last sunrise, she said: "Well, because I have a baby, it was not very long ago! It wasn't in the drunken haze it used to be. It was maybe a week ago, and I was up early with Otis."
