This is the natural progression of 'Tonight Show' host Jimmy Fallon's assorted warblings and big-time musical impressions: a full-scale musical medley co-starring Barbra Streisand. The songstress has a new album out -- her 34th! -- that's titled 'Partners' and features just a mess of duets between Babs and a bunch of male partners. Get it? Partners?
The legendary Barbra Streisand plays Seth Rogen's mom in the upcoming film 'The Guilt Trip,' and the pairing looks absolutely hilarious. Check out the first trailer for the road trip comedy, which hits theaters this Christmas.
