It was an epic surprise of BACHELOR proportions!
"The Bachelor" star Colton Underwood is the ultimate party crasher, surprising super-fans of the show at a watch party on Monday, hosted by our very own Ginger Zee.
What better way to celebrate both "National Drink Wine Day" and "Bachelor Monday" than with the Bachelor himself?
Just a few minutes into Monday night's episode, party-goers got the surprise of their lives when Colton walked in with a bouquet of bright red roses. There were peels of laughter and piercing screams after he said, "Will you accept these roses?!"
Here's the moment Colton surprised the room:
But wait, there's more! Unknown to even Ginger, Colton had a few friends tag along from the Bachelor universe: "The Bachelor" season 21's Nick Viall, "Bachelor in Paradise" season two's Tanner Tolbert and "The Bachelor" season 13's Jason Mesnick.
The whole night was best summarized by Ginger in just four words, "BEST. BACHELOR. SURPRISE. EVER."
The Bachelor gang of four also had a little fun of their own at the viewing party. Tanner even got a little fence-jumping 101 from Colton:
Meanwhile, Nick posted to Instagram, "just in case Colton quits ... they brought stand-ins."
We also learned Nick is great with kids:
On walking into a viewing party filled with unsuspecting Bachelor super-fans, "It was a little intimidating," Underwood told "GMA." "But I knew back up and reinforcements were coming."
The guys also shed some light on what to expect on next week's "Hometown Dates" episode of "The Bachelor."
"Home-towns is tough," Viall said. "It's very personal; you're bringing in people you didn't necessarily sign up for it."
Asked about who he is giving the final rose to? The Bachelor's lips are sealed.
"The Bachelor" airs Monday nights at 8 p.m. ET on ABC.
