Maybe these pals aren't as close as we thought!
Even Ryan Lochte was in the dark about Michael Phelps' secret marriage!
The Olympic gold medalist appeared on Hollywood Today Live on Friday to talk about his role on this season of Dancing with the Stars, but he also made a revelation about his teammate's wedding to Nicole Johnson.
"I had no idea. He said he was going to get married like a year after Rio and everything, and apparently he was already married? I don't know," Lochte confessed. "I don't think anyone was invited."

Despite not being invited to his pal’s nuptials, Lochte, 32, said that he will invite Phelps to his own upcoming wedding to fiancé Kayla Rae Reid.
"Yes, I'll invite him," he laughed.
ET confirmed on Wednesday that Phelps married Johnson on June 13, obtaining their marriage license in Arizona.
Johnson posted a photo to her Instagram on the day of their actual wedding back along with the caption, "Such a memorable night with my lil fambam boomer obviously didn’t want to hold still."
