Michael has been in the news in recent days after he called out Kylie Jenner, saying she only gives credit to certain designers who are either extremely well-known or who have paid her for an endorsement. Jenner had posted on Instagram thanking Balmain creative director Olivier Rousteing for a custom birthday dress, which apparently got under Costello's skin.
Lala had thoughts on the controversy and she decided to weigh in on it.
"I trolled Kylie's gram and found this. What a clown. This dude. I literally blew him up to make my custom wedding dress-he would have gotten all the 'tags & @'s' he's talking about. But I never heard back from him… why? Because I'm not 'big enough.' So cool out, Costello-you do the same sh*t," she wrote.
Michael didn't sit back, however. He responded that they had been in contact but opted not to work together.
"You wanted us to dress you and we passed. You didn't want to buy anything we also confirmed an appointment for you and it was a no show! Why are you complaining a whole year later? God bless," he wrote in response.
Lala blasted back, including the text messages and saying that he had made her point. She noted that he had "passed" on working with her just like Kylie had "passed" on him, advising him to "get over it."
Lala was set to marry her fiance Randall Emmett on April 18, 2020, but the coronavirus pandemic put her plans on the backburner.
Lala hasn't shown off the gown that she did eventually decide on, but a few months ahead of the big day, she shared a behind-the-scenes wedding photoshoot of her wearing a floor-length gown walking next to Randall in a black tuxedo on Instagram. Fans will have to wait until the two finally get the chance to tie the knot for the real deal.
While the couple appears to be going as strong as ever, a few weeks ago, Lala deleted all of the pictures of Randall from her social media account, causing some fans to worry that the two had called their nuptials off. She later confirmed that they were still together and had just had an argument, as The Inquisitr previously reported.
