As OK! readers know, the couple has reportedly been linked together since 2013 but decided to keep their relationship under wraps, even though Katie split from ex-husband Tom Cruise seven years ago in 2012.
But after six years of staying behind closes doors, the pair made their grand red carpet debut at the 2019 Met Gala on May 6!
"It was my dad's first Met Gala," Corinne said before adding that she felt "cool" for attending the prestigious fashion event before her father.
