Blue Bloods fans can always count on star Donnie Wahlberg to share behind-the-scenes footage from set, and this week was no exception. The NYPD drama normally has a more serious tone, but the New Kids on the Block singer took to Instagram to share a must-see blooper that has fans laughing out loud.

In last week’s episode, “Collision Course,” Donnie’s character Danny Reagan and his partner Melissa Baez (Marissa Ramirez) walk up on Sumaya Bouhbal after a car accident. The actress, who had a guest-starring role in the episode as Trina, accidentally lets some choice language fly and says, “Oh, I can’t curse on this show.” Donnie laughs and admonishes her by saying, “This is CBS! This is not Showtime! This is not Netflix!” He and Baez return to their car to reshoot the scene.

Donnie shared the funny behind-the-scenes clip on his Instagram account. Watch it here, but it does have NSFW language! Donnie wrote this message: “Happy #BlueBloods Friday! A little hilarious behind the scenes blooper from tonight’s all new episode — with an amazing guest appearance by the incredibly talented (and very funny) @sumaya.nazar777. So fun! 😂💯👑🎬🎭 See ya tonight! @marisachicaramirez @sumaya.nazar777 🎥: @jpphotography09”

Fans couldn’t stop commenting about the clip and left messages like:

• “Sometimes you just can’t control what comes out your mouth! She felt that hit in her soul 🤣🤣”
• “It’s all good you let it slip 😂😂😂😂”
• “I’m dying over ‘this is CBS not NETFLIX’ 😂”
• “Hahahahahhaha whoopsie daisy!”

Blue Bloods is back with an all-new episode on Friday, March 10, and special guest star Lyle Lovett reprising his role as Texas Ranger Waylon Gates. Tune in to CBS at 10 EST/9 CST, or stream on Paramount+.
