Long before he stepped onto the set of The Bachelor, Jason Mesnick had already found the love of his life. Without a doubt, his 4-year-old son, Ty, "is his first priority," former contestant Jillian, the season's third runner-up, tells Life & Style. "Jason's a wonderful father."

Now, Jillian reveals in an exclusive interview that Jason, 32, has finally found a partner to help fill the emotional hole created when he and Ty's mother divorced.

Ultimately, Jillian admits, she wasn't the one for Jason, but she's confident that Jason's final pick -- which comes down to bubbly, seductive Molly, 24, and down-to-earth knockout Melissa, 25 -- will be the best decision for both the single dad and his mini-me.
