Korean-American Lydia Paek must be the envy of Korean pop fans. She snowboards with members of A-list boyband BigBang and counts rapper CL of girlgroup 2NE1 as her pal.

No, she is no lucky fangirl. The bubbly Park, 25, is a bona fide musician, who pens and produces tunes for her labelmates BigBang and 2NE1 at mega artist agency YG Entertainment.

Signed to YG since 2011 as a songwriter, she has co-written tunes such as 2NE1 hits Ugly and I Love You. She is also a talented dancer who has demonstrated her grooves in BigBang rapper G-Dragon's music video One Of A Kind and a singer with a big, soulful voice.

On her own YouTube channel, which has more than 167,000 subscribers, she covers songs such as Sam Smith's Not The Only One and Chris Brown's Fine China.

Watch her perform here at Saturday's Shine Festival Performance Showcase, which is organised by National Youth Council. She will be at the stage outside Ngee Ann City along with local artists such as Charlie Lim and Weish, from 7.30pm to 10pm.

Paek says it is a blessing to be work with the YG artists, whom she says are hardworking, talented and have "great hearts".

One of the YG's sweethearts is BigBang's vocalist Daesung.

Recalls Paek, who shuttles between Seoul and her hometown in Los Angeles: "One time I mentioned that my skin is so bad, and Daesung recommended a skincare brand. The product was expensive. The next time we had a recording session, he bought me the skincare set. He has such a kind heart."
