Ryan Reynolds, Scarlett Johansson's marriage on the rocks?

New York, Nov 20 (ANI): It looks like all is not well between Hollywood couple Ryan Reynolds and Scarlett Johansson.

A source close to the couple says they are working through relationship 'troubles' caused primarily by work schedules that keep them apart, reports the New York Daily News.

The couple's tribulations may be the reason Reynolds did not make a cameo on "Saturday Night Live" when his wife hosted the show last weekend.

In October 2009, Johansson put in a surprise "SNL" appearance when Reynolds was the show's guest host.

Reps for Reynolds and Johansson have, however, denied that the actors' marriage was troubled. (ANI)
