Scarlett JohanssonJust weeks after rumours of engagements, Scarlett Johansson’s relationship with Ryan Reynolds is rumoured to be in trouble because of their busy work schedules.

Ryan was at the Berlin Film Festival last week promoting his new film Fireflies in the Garden but had to fly back to New York to promote his other film Definitely, Maybe just as Scarlett arrived in Germany for the premiere of her film The Other Boleyn Girl.

A source told the New York Daily News that this week’s jetsetting isn’t unusual for the busy pair: “They haven’t spent more than a day in the same city in months.”

Busy work schedules are also said to have been to blame for the end of Scarlett’s previous relationship with Josh Hartnett.
