New Delhi, Nov 21 : Scarlett Johansson and hubby Ryan Reynolds are desperately trying to start a family.

The couple, who got married in an intimate ceremony in September, are even discussing the best time for Scarlett to conceive, reports China Daily.

"Scarlett and Ryan are madly in love and want to start a family sooner rather than later.
