Blake Lively recently came under criticism for being "racially insensitive" when she shared an image of herself on Instagram with the Baby Got Back lyrics "LA face with an Oakland booty".
But she has now received the backing of the author of those words, Sir Mix-A-Lot himself.
The lyrics were taken as a reference to her saying she has a pretty face and a plentiful bottom as the image showed pregnant Blake from a front and rear view on the red carpet at Cannes.
Sir Mix-A-Lot told New York Daily News that he sided with critics if she was just saying that she had gained plenty of weight, but he believed she was simply saying how proud she was of her curves.
He said: "I don't think she'd wear that dress if she thought that booty is horrible -- and to me, it ain't horrible."
Of the backlash, he continued: "I don't get it at all. She's saying she's proud of her butt. I'm glad she embraced the look, because that's what I wanted (with the song)."
"All I would say to the critics is let's better understand the context of what she said.
"If what she's saying is 'I have this butt that Mix-A-Lot was talking about in Baby Got Back,' that's a good thing. She's saying I've embraced this ideal of beautiful.
"However, if what she's saying is, 'I cannot believe I got this fat, this is horrible,' then I agree with the critics."
He said he was glad that she did not pull the image down from Instagram following criticism.
