The former Spice Girl - who has a two-year-old son Beau with singer-turned-chef Jade Jones - insists she has a soft spot for the actor and a certain Canadian crooner.
She said: "I adore Michael Buble and Ed Westwick from 'Gossip Girl'."
Just as Emma is attracted to the two famous heartthrobs she also admires Beyonce Knowles.
The 34-year-old star admits there is only one girl band she would want to be in apart from the Spice Girls and that's Beyonce's former group Destiny's Child.
She added in a webchat with MySpace: "I loved Destiny's Child, I would like to shake my booty with Beyonce and the girls."
Meanwhile, Emma has revealed she met up with her former Spice Girls bandmate Victoria Beckham earlier this month to speak about the upcoming musical based on the band's songs.
She told Closer magazine: "I met up with Victoria when she was in London a couple of weeks ago and it was like no time has passed at all. She's always so much fun and a very supportive friend. She's never changed. We sat around and listened to our old hits to see how they would fit into the musical. We never get bored of them!"
