Solange Knowles covers the August issue of Lucky magazine, and the 28-year-old singer opens up about her smackdown on Jay Z in an elevator back in May.

Calling the altercation "that thing," Beyonce's little sister added:
    "What's important is that my family and I are all good. What we had to say collectively was in the statement that we put out, and we all feel at peace with that."

A week after the footage leaked online, the trio said in a statement, "As a result of the public release of the elevator security footage from Monday, May 5th, there has been a great deal of speculation about what triggered the unfortunate incident. But the most important thing is that our family has worked through it. Jay and Solange each assume their share of responsibility for what has occurred. They both acknowledge their role in this private matter that has played out in the public. They both have apologized to each other and we have moved forward as a united family."

Rumor has it Solange confronted Jay about cheating on Beyonce, and last month Life and Style's cover story all about Jay Z's affairs. Apparently Hov has gotten down with Rihanna, Rita Ora, Rachel Roy and the former Miss Belgium, and the mag reports that Bey is "so sensitive and insecure" about it that she's close to a meltdown.
