Selena Gomez has been scared by the 5.9-magnitude earthquake in Bulgaria's capital Sofia, she admitted in a tweet, in which she also apparently mistook Bulgaria for Italy.

The earthquake in Western Bulgaria had a magnitude of about 5.9-6.0 on the Richter scale, up from the initial reports of 5.8 and struck at 2:58 am Tuesday morning. Its epicenter is located about 6 km from Pernik and is at a shallow depth, making the shocks felt even stronger.

In the aftermath of the earthquake, fans from around the world became alarmed about the fate of their idol, Selena Gomez, who is in Bulgaria to shoot a new movie.

Initially, one of the most popular topics on Twitter was #PrayForSelena, after the fans quickly connected Bulgaria with her name. They later added the hash-tag #PrayForBulgaria which also gained huge popularity.

Selena Gomez assuaged the fears of her fans in a tweet that came Tuesday afternoon.

"Thank you for all of your concerns!! Earthquake was scary but thankfully everyone is ok. Praying for Italy," Gomez wrote on her Twitter profile.

In her post, the Hollywood starlet seems to be mistaking Bulgaria for Italy, which also saw major earthquake several days ago. Alternatively, she might be using her experience in Bulgaria in order to call for empathy with the victims of the Italian earthquake but the first scenario seems more plausible as Selena Gomez is already known to have been unable to identify Bulgaria's name correctly.

Selena Gomez and Ethan Hawke are in Bulgaria to shoot "The Getaway", a remake of the classic 1972 flick of the same name, which starred Steve McQueen and Ali MacGraw.

Selena is believed to be playing Fran, the young wife of a veterinarian who is seduced by a bank robber and then forced to go on the run with him.

With the intensification of the work of the Nu Boyana film studios near Sofia, formerly the state-owned Bulgaria's National Film Center, Bulgaria has seen a steady stream of Hollywood celebrities shooting scenes there over the past few years.
