Hong Kong celebrity couple Andy Hui and Sammi Cheng plan to tie the knot in August.

Their birthdays fall in that month, reported Nanyang Siang Pau.

Hui's elderly family members leaked the happy news to the media.

Hui, 44, and Cheng, 39, became good friends after they joined the same recording label in 1988 and embarked on their romance three years later.

Although the couple separated in 2004 after a 13-year relationship, they got back together last year.

The only bachelor of the four Cantopop Heavenly Kings - Aaron Kwok - was also reported to be marrying his model girlfriend Lynn Xiong Dailin in June.

It is learnt that the singer-actor has applied for two weeks' leave in that month from his company.

Kwok is said to be planning his wedding overseas and only a few of his friends knew the location.
