Jessica Simpson and Eric Johnson don't hold back when it comes to PDA—even on Instagram!

On NBC's Today Friday, Savannah Guthrie brought up the sexy, often-NSFW pics the fashion mogul posts to Instagram. "Those kind of happen sometimes," she said with a grin. "I am not shy to be in love with my husband!"

"Marriage is unbelievable," she added. "I couldn't be more in love, and he's given me to of the best blessings I could possibly imagine."

She's referring, of course, to the couple's 20-month-old son Ace and 2-year-old daughter Maxwell. "Having a boy and a girl, I'm—I'm blessed,' she gushed. "They inspire me."
