Lily Aldridge felt "giddy" shooting her Bulgari campaign.
The 30-year-old model has been named the new face of the brand and she admitted donning "millions of dollars" worth of jewellery for the advertisement pictures were a "dream come true" - though she felt nervous when she realised their value.
She said: "I mean, getting to wear these millions of dollars worth of jewellery is every girl's dream come true.
"It's really exciting and then when you find out the prices you kind of get all giddy."
Lily - who will lead global campaigns for the brand for the next year - admits her Italian heritage means working for Bulgari is a huge "honour".
She said during a news conference unveiling her spokesmodel role: "I am Italian, my family comes from Italy so to be the ambassador of such an iconic Italian brand is such an honour for me."
The Victoria's Secret beauty admitted Bulgari have been "very generous" with her, gifting her two rings, one from the Serpenti collection and the other from B.zero1.
She noted of the latter: "They gave me this ring while shooting the campaign, and I wear it every day."
But Lily - who is married to Kings of Leon rocker Caleb Followill - also has her eye on another piece in the collection.
She said: "I've been dying to get one of these serpentine chokers forever. It's something I've wanted for a long time so maybe my husband will read this and buy it for me."
Lily follows in the footsteps of Carla Bruni Sarkozy, Julianne Moore and Rachel Weisz as the face of the brand and knows sh has "big shoes to fill".
She said: "Those are some pretty big shoes to fill, a First Lady [of France] and Oscar winners.
"But it really is a dream job. I feel like I'm in amazing company."
