It's safe to say Viall won't be texting any of his exes a happy birthday!

The future newlyweds both commemorated their engagement news on Instagram, sharing a photo set that they both captioned, "For the rest of my life it's you."

Several celebs and fellow members of Bachelor Nation congratulated the happy couple, including "Selling Sunset" star Chrishell Stause.

"Bachelor In Paradise" alumna Natasha Parker highlighted her favorite photo in her comment; "that third photo kind of love," she wrote. Joy can candidly be seen with her head thrown back in laughter!

"The Ultimatum" star Madlyn Ballatori also offered her congratulations.

Viall's former fiancee Vanessa Grimaldi also entered the chat with her well wishes; the duo got engaged on his season of "The Bachelor" six years ago!

"the most beautiful night," the couple's pal Victoria Fuller commented. "ily guys sm. congrats to my people!" Fuller and her boyfriend, fellow Bachelor Nation alum Greg Grippo were hanging out at Viall's house for a game night where they were later seen getting cozy in Viall's TikTok account of the night. The TikTok had been posted prior to the on-screen conclusion of Fuller's season of "Bachelor In Paradise."

The future Viall's big night wasn't only shared with members of Bachelor Nation! One of the couple's pals commemorated the post-engagement gathering with a sweet TikTok!

Content creator Natasha Bure, who is the daughter of "Full House" star Candace Cameron Bure, was also on hand to celebrate the couple's engagement. Not only did she comment her warm well wishes on their Instagram photos, but she also was among the guests to celebrate their big moment!

Bure is a fixture on TikTok. At the end of last year, she took to the app to commemorate her happiest and most triumphant moments! According to our report on Bure's TikTok, she mentioned going through two breakups that would "change [her] life."

She seemed to be feeling anything but sadness as she commemorated her friends' big night!

In the 30-second clip, Bure captured moments of the couple excitedly walking into what appears to be a surprise party, the future Mrs. Viall showing off her ring, and the couple pouring champagne!

"Ahh these cuties are engaged!" Bure captioned her clip. "@nnataliejoy @Nick Viall it's SO beautiful to witness your love for each other. CONGRATULATIONS!!!"

"I was not a Nick fan in his bachelor era, but man has my opinion changed," one of Bure's followers commented on her TikTok. so happy for them!"

"This proves that age DOES not matter," another follower commented, "with an 18 year age gap you can still find PURE happiness and love." Viall is 42 and Joy is 24.

"I've never been so happy for a couple I don't even know!," another follower wrote.

"Just shows every bump in the road still brings you to right where you're meant to be all along," another follower commented.

The couple began dating two years ago. According to People, it was Joy who took the big leap and decided to message Viall on Instagram! Last summer Viall shared details about his now-fiancée's choice to hop into his DMs.

"My current girlfriend slid into my DMs," he told E! per People. "Real clever, it said 'You're unreal.' I guess it was funny. I was more curious, wondering why I was so unreal," he said.

Joy has appeared on several episodes of Viall's podcast "The Viall Files."
