The 40-year-old reality star gave her thoughts on all the hilarious comparisons that have been cropping up -- which Justin himself pointed out when he posted a shot of the two side-by-side on Instagram, though it's since been deleted.
"I do see some resemblance to my former hairstyle -- Justin's is a current take on it, yes!" Kate tells Cosmopolitan
. "And it's OK, he can have it!"
"Honestly, for me there wasn't a lot of 'styling' that went into it," she adds about how she achieved the memorable look. "It was more of a way to avoid having all-day bed head when my focus was on eight kids, all of whom were 5 years old and younger. I got up and it looked the same as when I went to sleep! With this style, I think Justin may have more time to focus on his music and less on his hair!"
Kate says Justin's acknowledgement of her on Instagram, however brief, has made her a "cool mom" -- especially when it comes to her 14-year-old twins with her ex-husband, Jon Gosselin
, Cara and Madelyn.
"My girls are beyond thrilled that he Instagrammed pics of us," she admits. "To top it off, Mady found his Instagram at the same time as I did this morning -- on the bus on the way to school, no less. Her response was, 'MOTHER, WHAT THE HECK?' in all caps, which I interpreted as approval and excitement!"
Interestingly enough, this isn't the first encounter the mother-of-eight has had with the 21-year-old "What Do You Mean?" singer. The unlikely pair actually met a few years ago.
"All I remember was that he was really polite and sweet," she recalls. "I applaud him for a whirlwind, successful career that began when he was very young. Everyone makes mistakes, and they never go unnoticed when you're in the public eye, but as a mom, I wish him the very best in everything he does in life!"
