AceShowbiz - Jenna Bush Hager doesn't wear underwear. The 40-year-old star was left red-faced when her "Today with Hoda and Jenna" co-host, Hoda Kotb, told the studio audience that she had just learned her friend always went commando.

"I was a little surprised because Jenna and I know a lot about each other," Hoda revealed. "I just had a little shock with it," she added while explaining she had "noticed" right before the show when the pair went to get changed for the programme.

Jenna - who is the daughter of former US president George W. Bush and his wife Laura - exclaimed, "You promised me you wouldn't do this! There's a lot of people here!" She then jokingly added, "I'm sure my mom has never been more proud."

And the mother-of-three insisted there were "a lot of pros" to not wearing underwear. She said, "I think it makes a more pretty silhouette! I also think you don't have to pack as much. There's a lot of pros to it!"

However, Hoda insisted there were downsides too, though she could see the benefits. She said, "It actually does make life a lot easier. [But] it's a lot of washing of clothes, over and over." But that didn't seem to bother Jenna too much, "[Hoda] said, 'Do you wash your clothes' and I said 'Yes, I do.' But it's also not like I'm sharing your jeans with you. Though I do steal Savannah [Guthrie]'s pants on occasion."

She then asked Hoda, "And I do want to borrow that red suit of yours. Can I?" Her pal replied, "Yes, you can, anytime." Jenna joked, "I'll wear underwear."
