"#PositiveVibesOnly", the 37-year-old reality star captioned the shot.
The reality star's personal life hit a rough patch this week as news broke that her National Basketball Association player boyfriend Tristan Thompson has apparently been filmed cheating on her at various points throughout their one-year relationship.
The mum-of-three wrote in the caption: 'I deleted some vacation pics because I didn't like the vibe on my page but I re-filtered them and reposting some!
Kim and her friends rented a party bus to bring them to the event.
The Daily Mail noted that Kim's Instagram followers were harsh in their comments about Kardashian seemingly ignoring Khloe's drama as she posted bikini photos.
Kim re-shared a picture of herself wearing a bright pink bikini and walking on the beach alongside Kourtney, who wore a navy string two-piece.
Dream is Kim's brother Rob Kardashian's daughter, whom he shares with Blac Chyna.
Glad Kim K had a good time looking back, though!
Kardashian went on to share in several videos and photos that she was not "worried" about running into people because she felt "good" about her conscience.
The Keeping Up with the Kardashians family is known for having outspoken views.
The pictures, which were posted before Khloe's crisis became public, however, continue to feature on Kim's social-media page.
"They're incredibly happy for Khloe, but it's the worst timing for Tristan to be accused of cheating on her", explained the source.
