While speaking with Entertainment Tonight at the taping of her Men Tell All special earlier this month, Thurston, 30, shared some advice for Young, 28, ahead of her stint as the next leading lady for the Bachelorette franchise.
"I've spoken to her as much as I can because I know it's any day now they're gonna take her phone away," Thurston said of Young, who is set to begin filming her season sometime later this summer. "I think the biggest advice I've given her is to just be open. Don't close yourself off too early. I think guys can surprise you ... weeks later when you don't expect it."
Thurston also singled out one previous contestant from her season who she believes would make a great match for Young — IT consultant Josh.
"I actually think Josh would be a good match for Michelle for sure," Thurston explained. "They just have very similar personalities. He is such a sweetheart and I think that's what she's looking for, someone who's just so kindhearted. That's something that Josh really offers."

For Thurston's season, Kaitlyn Bristowe and Tayshia Adams stepped in to host the reality dating competition series after Chris Harrison's exit, though it is not currently known if they will return when Young searches for love in the fall.
Describing her role as a co-host as a "pinch-me moment every single day," Adams, 30, told ET of hosting once more, "Will we be back for Michelle's season? We don't know, but we sure hope so," while Bristowe, 36, agreed, saying, "We have had so much fun together."
The Bachelorette airs Mondays (8 p.m. ET) on ABC.
