Accompanying Ha were her three children and her parents.
Her family posed for photos on Kiss Bridge, a new selfie spot inaugurated last December.
Located on the southern tip of the island, the bridge has been praised by CNN Travel "as a place for kissing, not crossing" thanks to its unique design.

The bridge has also received praise from famous websites such as Travel+Leisure, Travel Weekly, and Asia Today.
Crafted by Italian architect Marco Casamonti, the design of the bridge took inspiration from 'The Creation of Adam', the classical fresco created by Michelangelo for the Sistine Chapel in Rome, and the love story of Nguu Lang and Chuc Nu, a folk tale about two young lovers who are separated by the Jade Emperor but permitted to meet once a year on the O Thuoc Bridge.
The bridge spans a length of over 800 meters (half a mile) and consists of two separate halves.
In the middle there is a 30 cm gap, a distance which can be easily crossed with an embrace, a handshake, or even a kiss, hence its name.
The distance between the bridge has been calculated so precisely that on Jan. 1 of every year, the sun will fall directly in the gap between the two halves, its investor property giant Sun Group said.
After visiting the Kiss Bridge, Ha's family dined at a restaurant in the south of the island.
Her family also stayed at a secluded resort on Khem beach with 375 beach-view villas.

Ha, 39, started her career in the entertainment industry in 2000. She is active as a pop singer, model, and actress.
Vietnam’s largest island Phu Quoc has been suffering a slump in visitor numbers last year as tourists voted with their feet amid soaring airfares, exorbitantly priced hotels and various scams.
However, the island has seen signs of tourism recovery during the New Year holiday.
