London, Dec 8 - Actress-singer Lindsay Lohan has brushed off speculation that she is dating Jason Segel. She insists that they are just co-workers.

These rumours started doing the round when paparazzi saw her leaving from Segel's home, reports contactmusic.com.

"Ha, ha. Now a meeting at a co-worker's home has turned into a new love interest! It's absurd! At least I am laughing at the ridiculous manifestations," Lohan wrote on her twitter page.
