Beyonce & Solange Attend Kelly Rowland's Secret Costa Rican Wedding Together Just Days After Her Elevator Attack On Jay Z -- See Radar’s Exclusive Photos Of The Nuptials!

Just days after Solange Knowles bizarrely attacked Jay Z in the elevator of The Standard hotel after the Met Ball, Beyonce reunited with her sister when the two took off for Destiny's Child pal Kelly Rowland's secret wedding in Costa Rica — and only RadarOnline.com has the exclusive photos.

Rowland, 33, tied the knot with Tim Witherspoon after announcing their engagement last December, in a very small and private wedding ceremony in Guanacaste, Costa Rica, on May 9 surrounded by their closest family and friends, including the Knowles sisters.

Noticeably absent was Beyonce's husband and the target of Solange's anger, Jay Z.

The photos obtained exclusively by RadarOnline.com show Rowland glowing in her white dress the moment she and Witherspoon say "I do."

According to an insider, Beyonce and Solange flew on a private jet together to Rowland's tropical wedding, arriving on May 8 and leaving May 10.

As RadarOnline.com previously reported, surveillance footage from an elevator at The Standard hotel leaked on Monday with a startling image: Solange, 27, erupting on her brother-in-law, punching and kicking him during a wild all-out attack in the elevator on the way down to the lobby.

The day of the nuptials Beyonce posted a black and white selfie with the caption, "Good Morning" before watching her BFF Rowland get married.

So not only have Beyonce and Solange apparently mended things — despite RadarOnline.com's report that Solange deleted all photos of Beyonce from her Instagram account after the elevator beat down — but Beyonce and Jay Z also put on a united front after the incident.

Beyonce and Jay took in Monday evening’s NBA game between the Brooklyn Nets and Miami Heat.
