The producer, who haspreviously collaborated with Madonna on her song “4 Minutes,” admitted to AndyCohen that “she’s like a real boss.”He continued, “You kind of be nervous because she’s like very stern.”

Timbaland added, “It’skind of like a challenge.”

Natalie quickly chimedin, “But she likes people who challenge her back.” The Game of Thrones’ starwho is currently promoting her latest Hunger Games film, Mockingjay Part 2, hasworked with the singer in the past. Madonna cast the 33-year-old in her 2012 directorialdebut film W.E.

Agreeing that the "Material Girl" singer likes a challenge, Timbaland said, “She really does. You can’t give into her. Andthat’s how she gets her... If you jump back, you’re weak."

Madonna isn’t the onlybig name Timbaland has worked with. The 43-year-old rapper has alsocollaborated with Justin Timberlake on his 2002 hit song “Cry Me a River.” When asked by Andy if Justin had discussed his former flame Britney Spears during the songprocess, Timbaland revealed, “Yes.” But that doesn’t mean the song was about the popstar! Instead, Timbaland said the song “was a mystery.”

And while Timbaland hasnever worked with Justin's ex, the “Sometimes” singer has been linked to Madonna.The two famously shared a kiss onstage at the 2003 MTV Video Music Awards.

Small world, right?
