Chinese actress Zhang Ziyi's daughter, Wang Xingxing, have found herself to be the envy of Song Joong Ki's girl fans around the world. It started after the former posted a photo of the "Descendants of the Sun" star carrying her 7-month old daughter on July 9.

The 30-year-old Hallyu star and "Memoirs of a Geisha" actress have reportedly joined forces in the United States for a cosmetic ad. With Hollywood as the backdrop, the highly anticipated ad is set to endorse the latest products of Chinese cosmetic brand, Proya.

"Your 'husband' is really a warm and lovely person," Zhang wrote on her Weibo account, the China's equivalent of Twitter, as cited by The Korea Times. "Xingxing, are you pretending to be cool (in Song's embrace)?"

It is said that Song and Zhang became friends, as they both endorsed the same cosmetic brand, Proya. In April, it was reported that the former got a record-breaking endorsement with the said Chinese beauty brand. The two-year contract is reportedly worth 4 billion won ($3.48 million).

The post shortly went viral, drawing in more than 13,000 replies as of July 10, Sunday. One of the many girl fans then commented on the said photograph, as cited by Yahoo! Style, "I want to be Xingxing! In her heart, Xingxing is really excited. Her father must be jealous."

Xingxing, who was born on Dec. 27, 2015, is the first child of Zhang and "The Voice of China" coach Wang Feng, 45. The couple got married in Hong Kong on March 2015.

Meanwhile, Zhang is set to star in 2017's "God Particle," an upcoming science-fiction film directed by Julius Onah. The film, which is scheduled to be released on Feb. 24, 2017, revolves around astronauts on board a space station who get isolated after a scientific experiment causes Earth to suddenly vanish.

Song, on the other hand, will show up next in the 2017 South Korean movie titled "Battleship Island." Helmed by Ryoo Seung-Wan, "Battleship Island" follows the story of more than 400 Joseon people who risk their lives to escape Hashima Island, the place they were forcefully taken to during the Japanese Invasion.
