In January, Lowndes and Lovitz were spotted in Honolulu taking photos of one another after they both guest starred in Hawaii Five-O together. "Who needs a selfie stick when your co-star is Jon Lovitz?" she Instagrammed at the time. "Throwback to one of the funniest and most random paparazzi moments 😂😂😂 #comedy #hawaii50 #tbt."

Lovitz shared this most recent photo just a few days after Lowndes posted a pic of a man with his hands between her legs. "There's a new man in my life," she wrote. "His hands are wise and tell a thousand stories... #smitten #hatersgonnahate."

Further alluding that she was dating an older man (Lovitz is 33 years her senior), she quoted the Thai proverb, "Old cows love to eat young grass."

She added, "And I love me some old cows... 😘"
