Heidi Montag was happy to hear former roommate Lauren Conrad say she misses her on an episode of hit reality TV series, The Hills.
"I was glad to hear it... I thought it was really sweet," Montag told Extra.
"That really brought a big smile to my face."
"Obviously I miss her a lot. She was my best friend for a really long time. One day hopefully we will be able to work through this."
Heidi and Lauren haven't been on good terms since she moved in with Spencer (on the season finale of The Hills' Season Two).
The feud escalated after Heidi Montag and Spencer Pratt were accused of spreading rumors of a Lauren Conrad sex tape.
