Single lady no more?
Kelly Rowland and fiancé Tim Weatherspoon enjoyed quite the Costa Rican vacation recently – but was it for their wedding?
The couple arrived in the country together last Thursday and were joined by some notable guests.
According to immigration documents first obtained by La Nacién, Rowland’s Destiny’s Child bandmates, Beyoncé Knowles and Michelle Williams, were in attendance as well as Beyoncé’s sister Solange and their mother, Tina.
Though the couple have yet to confirm their nuptials, they are known for doing things simply – and spontaneously!
“He asked me first on Skype,” Rowland said in December of the proposal. “And I was like, ‘We’re so far away from each other.’ But it was so late – I remember we were both just kinda like, honestly, just staring at each other. And he asked me, and it was just that simple to say yes. I was like, ‘I got my best friend to ride through life with.’ He really is my best friend.”
After departing from Costa Rica with Weatherspoon on Sunday, Rowland was spotted at the 2014 American Ballet Theatre Opening Night Spring Gala in New York City on Monday night.
