TAIPEI - Taiwanese star Ruby Lin has been photographed with what appeared to be a baby bump amid rumours that she is pregnant.

A video of Lin and her fiance, TV star Wallace Huo, on the Apple Daily Taiwan website this morning showed her in a loose, red shift dress and displaying a tiny protuding belly.

Lin has been facing pregnancy rumours since she and Huo confirmed on July 5 that they would wed in Bali on July 31.

Suspicion was raised as the two have dated for only six months.

While attending a jewellery event in Paris last week, Lin was also photographed with a clutch bag shielding her belly.

Apple's video showed Lin and Huo leaving a KTV lounge in Taipei with friends around 2am this morning. They were there for a birthday celebration.

Huo appeared to be tipsy and had to be helped by two male friends into a taxi.

"It looked low-key, with Lin wearing a facial mask," Apple wrote. "But the street was empty, and as a light wind blew, Lin's baby bump appeared more evident, completely seen for the first time. It would be impossible to hide it."
