Dina Hayek (born Collet Bou Gergis on June 10, 1982) is a popular Lebanese singer. She gained popularity with the release of her second album, Katabtellak.Hayek started her solo career in 1999, after being discovered by Lebanese composer George Marderosian.

She studied music at Kaslik University, before taking private courses for 3 years with Fouad Houad and two years with Rafik Houbaika, both Lebanese musicians. Her debut album, Sehr el Gharam - Magic Of Love, was released in 2003 under the Music Master International label, and included the single by the same name which was backed by Egyptian music channel Melody TV.

Hayek's commercial breakthrough came when she signed a contract with the Saudi record label Rotana. Her second album, titled Katabtellak, was released in 2005. It was a commercial success, and included the hit singles, Katabtellak, Helwi Mennak, and Darb El Hawa,.

Dina Hayek's third album, Ta'a La Albi, was released in 2006. It included the single by the same name. The album's commercial success paled in comparison with its predecessor, despite its first-rate quality.

Hayek admitted that some Rotana artists, such as Elissa, get more attention from the record executives than the rest. She was also disappointed with the promotional efforts made for Ta'a La Albi, which partly led to low sales figures in both Egypt and the Gulf region.

She voiced her disappointment with Rotana for claiming that they were not able to secure her a performance at the 2007 Hala Febrayer Festival in Kuwait, despite the fact the overwhelming majority of the performers were signed with them.

In mid-2007 she terminated her contract with Rotana. She is currently working on new material with the support from Hab Production. So far she has released three singles, including "Jarreb El Ghira" and "Bhebbak Ma Bensa Gharamak".

An active singer, Hayek has given a number concerts and festivals in Lebanon, Egypt and the Gulf region, partly thanks to her brother, who is her manager. Her voice got the attention of the LegendarySyrian singer, George Wassouf with whom she performed in many concerts.

She has also worked with Melhem Barakat in a few concerts.
