RITA Wilson is going to be one fun mother-in-law. A tipster told us that Colin Hanks (“Orange County”), Tom Hanks‘ son, recently got engaged to Manhattan-based publicist Samantha Bryant. “Rita gave Samantha a $10,000 handbag to congratulate them,” said our tipster. No word as to what Colin’s dad gifted the low-profile power couple. Reps for Colin and Samantha declined to comment.
