Blake Lively Meets Idol Emma Bunton Wearing Baby Spice Necklace She's Had Since Age 10: 'Is That Weird?'

The actress was surprised by the Spice Girls alum during an interview at Heart Radio

Blake Lively's a Baby Spice wannabe.

While promoting her new movie It Ends with Us at Heart Radio ahead of the London premiere, the 36-year-old actress was surprised by her idol, Emma Bunton, aka Baby Spice herself. When the Spice Girls alum walked in the room, Lively was shocked, telling the singer, "This is so crazy, you have no idea."

Even crazier? Lively was wearing the very same embellished "Baby" necklace she's had since she was a 10-year-old Spice Girls superfan.

At one point during the Friday, Aug. 9 episode, Bunton, 48, asked the Gossip Girl alum, "I did see a picture of you once. Did you dress up as Baby Spice?

"Quite often, quite often," Lively replied.

She then gestured to the jewelry piece around her neck saying, "I wore my necklace that I've had since I was 10. I literally keep it in a safe. It's like my wedding ring and this."

"Can I take a picture of you wearing my necklace?" the actress continued. "Because then my necklace is minted with you, like it's actually been on you. Is that so weird? Is that weird?"

Bunton happily agreed and the duo took a photo holding up a framed childhood snapshot of Lively at age 10, wearing the necklace.

The singer also shared that the fan-girling was mutual. "I've been a fan of yours as well," Bunton told Lively. "I've watched Gossip Girl back to front a few times."

Bunton was formerly in the British girl group the Spice Girls, which was formed in 1994 and dominated the pop music scene throughout the 1990s. Dubbed "Baby Spice," she was in the group alongside Mel B ("Scary Spice"), Melanie C ("Sporty Spice"), Geri Halliwell ("Ginger Spice") and Victoria Beckham ("Posh Spice").

While promoting her debut hair care line Blake Brown earlier this month, Lively told PEOPLE that she often channels the Spice Girls when choosing her outfits.

“I'm a pretty shy person, so if I'm going to go somewhere, I tend to choose a character,” she said. “It’s like, ‘What Spice Girl am I today? Or which character of Sex in the City?’"

She added, “Because I style myself, I was like, what's the sort of character that allows me to go out to something that's a lot of stimulation and attention [like the Super Bowl]… what’s the way in?”
