bought husband Orlando Bloom
a pair of silk boxer shorts to help him get "into character" in the bedroom.
The 28-year-old model - who has 10-month-old son Flynn with her actor husband - treated the hunk to the luxurious underwear for the pair to enjoy.
She said: "Well he had to get into character so I bought him these silk boxer shorts and it kind of helped."
Asked by TV talk show host Chelsea Handler what she meant by get into character, she replied: "For, you know, us. I don't want to tell you what he bought me."
The Victoria's Secret model also revealed baby Flynn is already showing an interest in music and dancing, in particular hip-hop.
She said: "He loves hip-hop. When I had him in my stomach, I'd play music and sometimes I'd put on hip-hop and dance around. So now, I put hip-hop on and he shakes his head - pretty funny."
However, the youngster could be set to become a star himself in the future, as Miranda admitted he loves grabbing the limelight.
She explained: "[During an outing], I was pulling the scarf over to cover him from the paparazzi, and he was pulling it down, like, 'Hey guys! Here I am.' "
