BLACKPINK's Lisa celebrated her stepdad's birthday recently, and her gift to him has netizens talking.

According to media outlets, Lisa attended her stepfather's 70th birthday party in Thailand on October 15. In the photos posted by Lisa's mother, the BLACKPINK member can be seen in a denim dress as she stands for a photo between her parents and presents a birthday cake to her stepfather.

What's catching attention is a box from the luxury watch brand TAG Heuer, the company where Lisa's rumored boyfriend Frederic Arnault is a CEO. The two have been facing dating rumors since this past July when photos of them dining together in Paris went viral online. Lisa and her rumored boyfriend were also allegedly seen together in Greece and at another restaurant in Paris earlier in this month.

The TAG Heuer watch gift to Lisa's stepdad is further fueling rumors as many netizens are speculating it's actually a birthday gift from Frederic Arnault himself. Photos also show Lisa wearing red and green hairpins, colors of the TAG Heuer logo. Previous rumors also say Frederic Arnault was recently in Bangkok to open the watch brand's first flagship boutique store in Thailand, and he and Lisa as well as her family were spotted boating on the Chao Phraya River that runs through the Thai capital.

Stay tuned for updates on Lisa and BLACKPINK.
