Beyoncé wrapped up the first leg of her [article id="1707855"]Mrs. Carter Show[/article] world tour over the weekend with pregnancy rumors still swirling.

Only weeks ago, [article id="1707684"]Jay-Z reportedly shut down[/article] the speculation, but when the singer sat down with the "Today" show, she played it coy instead of issuing a hard "yes" or "no" answer.

"What kind of rumor? Huh?" the singer said with a laugh when interviewed backstage at the Sound of Change Live charity concert in London. "I don't know what you're talking about!"

Her bite comes days after she posted a photo of herself sipping wine with Hova while trekking the globe, leaving fans to further speculate without a firm answer from the singer herself. Drinking wine isn't the only thing she and her rapper hubby have done together in the last few days. On Saturday night he joined her onstage in London at Twickenham Stadium, where they performed "Crazy in Love" together.

In addition to her Jay-Z duet, Bey also performed "Run the World (Girls)," "Single Ladies," "If I Were a Boy" and "Halo." Other performers included Jessie J, Rita Ora, Iggy Azalea and Florence and the Machine. The benefit show raised $4.3 million for the Gucci-sponsored organization Chime for Change, which promotes female empowerment.

The day before the London show, Beyoncé played Antwerp, Belgium, closing out the European leg of the Mrs. Carter jaunt, giving fans the first full listen to "Standing on the Sun." "We've been saving this song just for y'all," she told the crowd before launching into the searing, island-influenced summer love song, co-written by Sia and Greg Kurstin.

Bey will have a few weeks off before the tour resumes again on June 28 at Los Angeles' Staples Center. She already seems to be enjoying her time off. On Sunday she was spotted in New Jersey with Jay attending [article id="1708327"]Hot 97's annual Summer Jam[/article].
