James, 27, shared a side by side photo of Lala, 29, next to a model wearing similar dresses.
"When you order online vs. when it arrives," was written at the top of the photo. The pic insulted Lala for looking worse than her counterpart, at least in the eyes of James.
He brought up Lala's enemy 50 Cent, 43, as part of the caption. "imma put this right here ..... fofty said leave it."
50 got into a war of words with Lala's fiancé Randall Emmett last month after he allegedly owed him a ton of money. The "In Da Club" rapper also made fun of her multiple times on social media.
The Grammy winner officially squashed his feud with the Power executive producer after he allegedly received the money that was owed to him.
