And she revealed how devastated she felt after she was dumped by her fiancé Roy Williams in the same week as she appeared on the cover of a glossy magazine a few years ago.
"I wanted that wedding. I wanted to be married. I wanted to have kids," she said. "At that time I was crazily talking about wanting five."
Now she's determined to make up for her own sadness by being as involved as possible in her friends' happiness – starting with her Destiny's Child pal, Beyonce.
She vowed not to miss the birth of the 30 year-old superstar's baby to husband Jay-Z early next year after she wasn't able to be around for another friend's child being born – something she has regretted ever since.
"I wouldn't miss the birth of Beyoncé's baby," she said. "I can't. I don't want to miss those moments.
"It's life happening to people that I love and I want to be a part of it."
