In an Instagram post on Thursday, Heidi put her stunning body on full display in a black swimsuit and heels.
The post drew its fair amount of admiring comments, including one VERY flirty post from castmate Lauren!
"Getting ready for the 'Single Ladies' video clip", Heidi's caption reads.
"Ummm, my offer still stands", commented the makeup artist, accompanied with a drooling face and love heart emojis.
We have just one burning question: What was Lauren's offer?!
