"Dancing with the Stars" diva Kym Johnson is celebrating the good times before her upcoming wedding to her fiance, former "DWTS" partner Robert Herjavec -- and she's doing it with a co-ed bachelorette party in the City of Sin!

The Aussie stunner flew out a group of gorgeous gals and boys, including Cheryl Burke and Carson Kressley, on Friday, July 29, to catch Jennifer Lopez's "All I Have" residency at the Planet Hollywood Resort & Casino. 
And it looks like the posse had a slammin' time!

The 39-year-old, who donned a white dress, tiara and veil, posted a smiling snap with her fun-loving group, "Best night with best friends @phvegas for J Lo's show#allihave @jlo πŸŽ‰πŸ‘°πŸΌπŸΎ"

Umm we want to go see Jenny from the Block with Kym and her crew! #jealous!

In addition to seeing JLo crush it on stage, it appears as if Kym had a run in with a fellow Aussie, superstar Nicole Kidman, who was also wearing white to the concert. Twinsies!

The beauty posted a few snaps from the A-list encounter, one of which she captioned, "And then I met Nicole Kidman πŸ™‰πŸ™ˆ what a whirlwind of a bachelorette I had."

Earlier in the night, the dancing queen posted a snap with the caption, "Let the fun begin! #bachelorette," from what appears to be a private jet (looks like they were traveling in style!), which they decorated in pink and polka dots for the bachelorette festivities.

Let the fun begin! #bachelorette

It appears as if it was a day of bridal festivities for the bride-to-be, having a bridal shower earlier in the day on Friday. The happy lady posted a slew of photos from her bridal shower earlier in the day that showed the blonde smiling with her mother, Florence Henderson and a few other famous famous.

Kym also had a bevy of beauties supporting her upcoming marriage, including her pro dancer pal Cheryl Burke, who was at all of the day's festivities. The bubbly bride posted a photo with her lady friends, who complemented her white ensemble by wearing pastels. Kym captioned the photo, "I'm so lucky to have The most beautiful friends. @kimallinson@cherylburke #melanieantunes"

Kym and Robert, who is 53-years-old, got engaged in February after dating almost a year. The duo met on the dance floor, of course -- "The Shark Tank" judge was paired up with the pretty lady for season 20 of "DWTS." The twosome two-stepped and clearly sparks flew!

Kym gushed about her main man to Us Weekly at the DWTS PaleyLive event on May 14: "He's such a great guy. We love spending time together."

Previously a source told the mag, "Robert adores her, and they are the sweetest couple. All of their friends are so happy for them!"

We're happy for them too!
