"Boy Meets World" star Matthew Lawrence and TLC singer Chilli certainly had a good time together at the beach in Hawaii ... but sources say they're not romantic.
Matthew and Chilli were spotted Monday on the beach in Waikiki. Some beachgoers tell us the two got in the water together and shared some intense convos while chilling on beach chairs.
A rep for Chilli tells us the two aren't dating or romantic, TLC had a show on the island, and Matthew and some pals came to watch ... the two are friends and linked up later.
We haven't seen Matthew out much since his ex-wife and "Dancing with the Stars" pro, Cheryl Burke filed for divorce about 6 months ago.
As we reported, Cheryl and Matthew were married nearly 3 years, before she pulled the plug back in February, citing irreconcilable differences. She noted they'd been separated since Jan 7.
Nothing like a trip and dip with friends to lift your spirits.
