Janelle Pierzina and Rachel Reilly can’t help but stir a commotion online about Big Brother 27’s mystery houseguest.
Janelle, 45, kicked off speculation on Tuesday, July 8, when she took to social media to share that she thought Rachel, 40, was returning to the beloved competition series.
“Ummmm Rachel’s phone goes right to voicemail,” she wrote via X. “It’s her, it’s definitely her!!!!”
One fan replied to Janelle, asking if she was joking about her claim. Immediately, the two-time Big Brother all-star doubled down on her beliefs.

“She [texted] me back saying she was at home. But I got to thinking. Rachel always calls me back. And [her husband Brendon Villegas] could be texting from a laptop responding to her texts,” Janelle responded before analyzing some of the clues from Big Brother about the identity of the mysterious houseguest. “The B in the study is for [Brenchel] the V is for [Villegas] her married name. The map was all her Amazing Race journeys….”
Later that day, Rachel posted an Instagram Reel reacting to Janelle’s theory.
“When Janelle keeps calling but I’m literally in Greece,” read text alongside a close-up of Rachel doing a lip sync.
The mention of Greece was a reference to Janelle’s infamous tweet, in which she claimed she was going to Greece when, in reality, she was returning for Big Brother 14 instead.
“Ever heard of Summer Vacation? 
,” the Big Brother season 13 winner added.
The following day, Janelle posted a video of her and Rachel together from a cruise they enjoyed together earlier this year.
“Me and Rachel on our next Big Brother cruise celebrating her to be the only Big Brother player to win twice. 
,” she captioned the clip.

The official Big Brother 27 cast dropped on Tuesday and includes 16 new houseguests competing for the $750,000 cash prize. A mystery 17th contestant will also be in the mix — but their identity won’t be officially revealed until the show’s 90-minute premiere on Thursday, July 10.
“So there’s a 17th houseguest, and you’ve all given a few guesses,” the official Big Brother account wrote via Instagram on Tuesday alongside a portrait of a silhouette. “Wonder who’s correct?

In addition to a surprise houseguest, Big Brother is introducing a new competition similar to last year’s AI Arena.
“It was so successful last summer, that we are bringing it back this season,” the show’s host, Julie Chen Moonves, exclusively told Us Weekly. “But it’s called the BB Blockbuster.”
