Smita Patil and Raj Babbar’s son, Prateik Babbar, is likely to tie the knot with his long-time girlfriend Sanya Sagar soon. The 31-year-old actor is set to get engaged with Sagar in Lucknow on January 22. Bombay Times has quoted a source close to Babbar saying, “The engagement will be a close-knit affair. Their families are tight-lipped about it, as Prateik wants to go a little easy and stay away from the limelight unless it’s work related.
