Kaitlyn Bristowe and Shawn Booth had to keep mum about their engagement before the season 11 finale of "The Bachelorette," which aired on July 27, but it appears that the couple found ways to be together in public without spoiling the ABC show's top secret finale. 

On Thursday, Aug. 13, Bristowe took to Instagram to share a picture of the couple in disguise. In the shot, the 30-year-old reality TV star is wearing a platinum blonde wig cut in a blunt bob with bangs, while Booth dons a shoulder-length black wig. Both of them are wearing sunglasses and hats. Bristowe captioned the snap, "Maybe the other week wasn't our first time out in public!!? #bonnieandclyde @shawn_booth18." 

Although the two may have been careful in concealing their identities while out in public, they still managed to spoil the reality show's ending after she accidentally shared a Snapchat photo of her with her fiancĂ© by accident. 

"I started having a panic attack," said Booth on "Jimmy Kimmel Live" about the incident. "I couldn't even breathe." 

A day after the finale, the couple was seen spending time together in New York City, and they appeared to be happy about being out in public together as they were photographed being very affectionate to one another. Since then, they have also shared numerous pictures of each other on social media, and earlier this month, the couple even went to Bristowe's hometown in Vancouver, Canada to spend time with her family. 

People magazine reports that the two told "Good Morning America" that they plan to spend time in Vancouver and Booth's hometown in Nashville before deciding where they want to stay. In Vancouver, the couple appeared to be more in love than ever as they rode bikes, had a picnic on the beach, and even crashed a wedding. 

As for their wedding, back in July, Bristowe told the magazine that she was thinking about having a destination wedding "because I'm so low maintenance." The couple has yet to announce a date for their nuptials.
