Bachelor in Paradise stars Derek Peth and Taylor Nolan got engaged this week.

The 30-year-old commercial banker proposed to Nolan while filming the show's Season 4 aftershow Wednesday, according to People.

E! News reported Peth popped the question with a Neil Lane ring valued at more than $60,000. The platinum ring features over three carats of diamonds and a pave diamond band.

Peth and Nolan competed on The Bachelorette Season 12 and The Bachelor Season 21, respectively, before appearing on Bachelor in Paradise. The pair immediately connected after meeting on the ABC reality competition.

"In Bachelor world, I never felt like I was the person that was desired but I like that I'm desired by the person that I desire," Nolan said in Episode 2.

"Every time I'm with Taylor I just feel really happy," Peth added. "I keep smiling and I'm really giggly and like a school boy again who likes a girl."

Bachelor in Paradise Season 4 premiered Aug. 14 following a delay in production. ABC resumed filming after finding no evidence of sexual "misconduct" between contestants Corinne Olympios and DeMario Jackson.
