Blake Lively is not only super-tight with Florence + the Machine frontwoman Florence Welch (photographed together at The Cosmopolitan of Las Vegas hotel grand opening on Dec. 31, 2010), but she’s also the band’s biggest groupie! "She's been to all of the shows that we've done in America and she flew out to Las Vegas just because I was performing there over the New Year," Welch, who performed at Lively's recent surprise nuptials to Ryan Reynolds, told E! Online, last year. "I love Blake. She’s a great girl." Lively, who bought pizza for the band when they first met, clearly agrees. "I think we love each other too much," Lively jokingly told Welch when the rocker interviewed her for Glamour. Nah, with these two, that doesn’t seem possible.
