Who is Daisy Kelliher's Sister, Bonnie? Meet the Chief Stew's Sibling (UPDATED)

UPDATED (July 18, 9:31 A.M.): During Part 1 of the Below Deck Sailing Yacht Season 4 reunion, which took place in the Watch What Happens Live with Andy Cohen Clubhouse, Daisy Kelliher revealed how her sister, Bonnie Kelliher, really felt about meeting the rest of the Parsifal III crew. 

"She loved everyone, I mean Bonnie is hard to not get on with," Daisy said. 

UPDATED (June 27, 10:11 A.M.): Daisy Kelliher's sister, Bonnie, stopped by Parsifal III on Episode 14 of Below Deck Sailing Yacht Season 4, which is aptly titled "Hurricane Bonnie."

During her time on the sailing vessel, Bonnie stirred up the drama by telling Daisy that she's "really suited" with Gary King (though she later said that her connection with Colin MacRae is "every girl's dream"), and she shared a kiss with deckhand Alex Propson in the van. Keep scrolling to find out more about Bonnie.

The original story continues below.

Over the past few seasons of Below Deck Sailing Yacht, we've become pretty well acquainted with chief stew Daisy Kelliher. Some of the drama has included a back-and-forth situationship of sorts between Daisy and deckhand Gary King and, more recently, a love triangle involving Daisy and Gary plus engineer Colin MacRae. 

We haven't, however, met Daisy's family, including her sister, Bonnie Kelliher. In the midseason trailer you can watch above, we get a sneak peek of the sibling making her grand entrance, and from what we can see, it is indeed quite grand. 

Daisy Kelliher Prepares for Bonnie Kelliher's Arrival 

In Season 4 Episode 12, Daisy asks Captain Glenn Shepard if it would be cool if her sister stays with the crew aboard Parsifal III when she comes to stop by for a visit. "My sister is in town and I was wondering if she could come for a crew night out and stay on the boat," Daisy asks Captain Glenn Shephard. 

"We can make it work," he responded. "I'd love to meet her." 

"Yeah, she's a good time," Daisy smiles, giving us a tease for what's to come. 

Later, before getting ready for bed, Colin announces Bonnie's forthcoming arrival to Gary, hilariously quipping: "Why don't you just go for Bonnie?" 

Bonnie Kelliher is coming to stir up some drama of her own 

In the midseason trailer, Bonnie is seen joining the crew for a fun night out and having a few drinks in the process. "So 20 tequilas ... and what are you guys having?" Bonnie jokes as they're all out to dinner. 

Further in the clip, while Bonnie rides home with Alex Propson, Mads Herrera, and Chase Lemacks, she and Alex go on to share a kiss (as BDSY fans may remember, the deckhand also kissed Daisy at the beginning of the season during a late night hot tub session).

"I was hoping the crew wouldn't be stupid enough to hook up with the chief stew's sister," Daisy quips in the clip as Mads puts her ear to the door of what's presumably a room where Bonnie is maybe hooking up with someone 

OK, now we really need to tune in next week when Bonnie makes her grand entrance aboard Parsifal III! 

Still to Come on This Season of Below Deck Sailing Yacht

Bonnie Kelliher seems to like boating as much as her sister 

Judging from her Instagram page, it looks like Bonnie enjoys traveling and being on boats as much as Daisy, with numerous photos showcasing that fact. 

From hula hooping by the beach to posing on dirt bikes in the desert, Bonnie is definitely the free spirit, often sharing photos of herself in sexy bikinis and taking exciting adventures.
