Jenna Bush Hager is an executive producer on the new series Line of Fire, airing Mondays on NBC.

The Today host filmed an Instagram promo with show stars Peter Krause and Tommy O’Brien, teasing her Secret Service code name from her time in the White House.

Jenna has previously opened up about the unique moniker from when her dad, George W. Bush, was President from 2001 to 2009.

Jenna Bush Hager fans have a lot to say about the star’s latest Instagram post.

The Today host is executive producing her new series Line of Fire, which airs Mondays at 10 p.m. ET on NBC. As part of the promo, Jenna filmed an Instagram video with stars Peter Krause (who plays Secret Service agent Mike Hollingsworth) and Tommy O’Brien (who plays Mike’s son and fellow agent, Micah) in the show’s makeshift White House.

“Twinkle is in the building,” Peter stated in the clip on October 12, referencing Jenna’s code name for when her dad, former President George W. Bush, was in office from 2001 to 2009.

“Please stop calling me Twinkle!” Jenna replied. “Can’t you just call me Jenna?”

“Sorry, ma’am,” Peter and Tommy answered.

Jenna also captioned the video with the special nickname.

“Once Twinkle, always Twinkle ✨,” she wrote. “My Secret Service code name followed me all the way from the White House to the set of LINE OF FIRE … ”

Fans gave “Twinkle” extra love in the comments.

“Protect Twinkle at all costs,” one person wrote in the comments. “We don’t play about Twinkle over here! ❤️,” another penned. “Do you still have Secret Service protection?” another follower asked.

Jenna has opened up over the years about being given the adorable code name from the Secret Service. In fact, when she shared the moniker with Andy Cohen on Watch What Happens Live in 2020, she explained that she’s still called “Twinkle” at the White House.

“When we went back to the White House with the TODAY show peeps, we walked in, and they were like, ‘Twinkle, welcome home,’ and everybody was like, ‘Twinkle?’” she shared at the time, per NBC Insider.

Well, we definitely need to know more about this!
