The 'American Idol' host, who split from 23-year-old personal trainer Shayna Taylor in December after 18 months of dating, appears to be smitten with the blonde beauty after being introduced to her by mutual friends at his lavish 40th birthday party in Napa Valley, California late last month, where they quickly hit it off.
The 'Keeping Up with the Kardashians' producer was spotted strolling around New York City with the Nashville-based model, who has an eight-year-old son, Levi, from a previous marriage, over the weekend.
An eyewitness told gossip website TMZ.com that the couple visited the Museum of Modern Art in Manhattan.
News of Ryan's new romance comes less than a year after friends predicted the media mogul was preparing to propose to Shayna.
Last summer, a source claimed: "Everyone before Shayna bored him. He's moving fast."
Another insider said: "They are so affectionate and sweet together. He's ready to settle down. Shayna came into his life at just the right time."
Ryan, who split from 'Safe Haven' actress Julianne Hough in March 2013 after three years of dating, previously admitted he is eager to find long-lasting love like his parents, Connie and Gary Seacrest.
Speaking last year, he said: "I look at what my mom and dad have had for 40-plus years - a fantastic relationship and great marriage. Someday I'd like that. They're my role models."
