Beyoncé and Solange 'flew to Costa Rica for Kelly Rowland's wedding'

They were pictured leaving in a car together without Jay Z, after Solange Knowles had viciously attacked her sister's husband last Monday.

Now it has emerged that just a few days later, Beyoncé and her sister made a getaway to Costa Rica, according to E! where they joined Kelly Rowland for her secret wedding.

UsWeekly report that Kelly's wedding was a 'quick, simple ceremony - only around 30 people,' that took place on Friday according to their source.

Meanwhile E! report that Beyoncé and Solange arrived in Costa Rica onboard a private plane around 7:56pm on Thursday 8 May, three days after the attack that took place in an elevator at The Standard Hotel in New York.

Local paper La Nación reported that their mother Tina Knowles, Destiny's Child member Michelle Williams and Kelly's fiance Tim Witherspoon were also in Costa Rica, prompting rumours they were there for Kelly and Tim's nuptials, which have now been confirmed by UsWeekly.

Beyonce added further fuel to the fire by posting a picture on her Instagram, looking as though she was dressed in a bridesmaid outfit.

However, there was no sign of any distress from the pop star in the picture, nor has there been any comment from the star's representatives about the attack last week.
