The switch is official, as Catherine Giudici proudly declared, “The best day of my life. I’m a Lowe!” to her 500,000 Twitter and Instagram followers. The newlyweds have just returned from a romantic honeymoon in the tropics, and Sean says he is “so freakin’ happy” with how it all turned out. Married life does seem to suit the couple rather well. Since returning from her honeymoon, she’s been posting photos of her and her new husband cuddling in bed, as well as photos from her wedding. The two had their doubters when he picked her on The Bachelor, but he was true to his word that she was the one – and he was willing to wait for her. Seriously. They passed a premarital sex polygraph . In making the name change, Cat follows in the footsteps of Bachelorette Trista Rehn, took her husband Ryan Sutter’s last name after their marriage. Molly Malaney, who married former Bachelor Jason Mesnick in 2011, did the same, although Ashley Hebert did not take J.P. Rosenbaum’s last name.
