Currently a radio DJ with MediaCorp 987FM, Rosalyn co-hosts the morning drive-time show, The Rude Awakening on weekdays from 6 - 10am.

Rosalyn was last seen on TV hosting Channel 5's reality variety show, 'Girls Out Loud', which caused a buzz in the community for its quirky spin on life. She charmed the audience each week with her sassy wit, straight talking ways and wicked sense of humour.

She is hip, versatile and reaches out to the masses - from the very young, to the sophisticated, as seen from her various works such as being the face of the McDonald's TV commercial 'FANtastic' to hosting events for Swarovski and Porsche. Rosalyn is also currently part of Dove's 'Campaign for Real Beauty' which features real women comfortable in their own skin.

In 2005, Rosalyn beat 9 others to emerge the winner at the Singapore leg of the MTV Whatever Things Show Host Contest. She went on to represent Singapore at the Regional Finals in Bangkok, joining winners from China, Philippines, India, Indonesia, Malaysia, and Thailand. She bagged the 1st Runner-Up title.

As a definite star on the rise, Rosalyn was awarded "Breakout Star Of The Year" at the first ever ELLE Awards 2006, beating other nominees like artiste Felicia Chin and Samantha Tan from Eric Khoo's Be With Me.

She is also a trained dancer who used to perform professionally. In her free time, Rosalyn enjoys cooking, pool, and a good old laugh.
