Scarlett Johansson and Ryan Reynolds About To Breakup?

Scarlett Johansson and Ryan Reynolds are on the verge of splitting up, a source tells Gatecrasher :

The gorgeous duo are reportedly working through relationship "troubles" caused primarily by work schedules that keep them apart.

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. Though we hear producers were interested in having the upcoming "Green Lantern" star make a similar cameo, Reynolds declined.
