Chrissy Teigen thinks a threesome with Cardi B and Rihanna would be "ideal."

The 32-year-old model was taken aback when the Bodak Yellow hitmaker rapped in her song She Bad that she wanted to get frisky between the sheets with the Bajan beauty and the brunette star, but it looks like she's starting to come round the idea now - even though she'd "probably just sit in the corner watching."

Speaking on Watch What Happens Live with Andy Cohen, Chrissy said: "Literally that threesome. I'm like: 'Omg, I'm so boring.' 

"And I would just literally be the one in the corner watching, I feel like. Any group I'm lumped into Rihanna with, I'm very happy."

However, although she's quite shy when it comes to discussing threesomes, Chrissy isn't afraid to open up about her bedroom antics with her husband John Legend. 

Speaking about their first date, she said: "We were on a music video set all day together, and then I went to one of his shows, and then... yeah."

But the couple have two children - two-year-old Luna and four-month-old son Miles together - are too "tired" now to get their groove on in the bedroom. 

Chrissy said recently: "If he performs somewhere, and I go, I'm like, 'Oh he's sexy.' It doesn't matter who you are, even if you're a sexy R&B crooner or an ex-swimsuit model, you're just tired. We still have that passion for each other, but are we doing it randomly in a dressing room? No! We'll get back into it again."

Regardless, the 39-year-old singer still likes to shower his wife with compliments. 

Chrissy explained: "John tells me I'm sexy all the time. Honestly I fight it because there's only so much that someone can say or do before you're like, 'I know you're not telling the truth.' 

"But he really pushes it and he wants me to know that he loves my new body or he loves the way my skin feels. When I'm feeling totally filthy, he always lets me know that he is still totally turned on by me, which is great."
