Earlier today (Nov. 8), Ryan posted a drawing of the two of them with a caption that read, simply, "ENGAGED!" The two have had an on-again, off-again relationship for years.
This will be Ryan's second marriage and the fourth for Mellencamp, 67. "She hates me to death".
Meg Ryan is ready to say "I do". The pair split after three years, according to People, and were seen together off and on before officially reconciling last year. When asked why, he told Stern: "I think it's because I'm a child".
