Aurora Culpo doesn’t need anyone’s approval of her new romance—including pregnant sister Olivia Culpo.

The Barely Filtered podcast host teased her new relationship on social media, posting a photo of herself planting a kiss on her mystery man’s cheek on her Instagram Stories March 23 along with the hashtag “#LOML” (a.k.a. “love of my life”)—much to her younger sister’s chagrin.

“Too soon for this hashtag Aurora,” the Miss Universe winner wrote in a direct message shared on Aurora’s Instagram Stories, to which Aurora replied, “Lol no it’s not.”

In a follow-up screenshot, the 32-year-old—who is expecting her first baby with husband Christian McCaffrey—continued to playfully scold Aurora, 35, writing back, “It’s giving: ‘I’m not thinking with my right mind.’”

But the sisters evidently had different points of view as Aurora cheekily dismissed Olivia’s concerns with hashtags including “#snoozefestsister” and “#pregnancybrain.”

Aurora—who shares kids Remi, 6, and Solei, 4, with ex-husband Michael Bortone—previously dated Bethenny Frankel’s former fiancé Paul Bernon, though the pair parted ways in July after a two-month romance.
