I found this artikel at the Annie and Liam Fansite! So I thought I would share it with u guys! Credit goes to:link
♥Their story in Season 2:
Liam never told anyone who he slept with, leaving everyone to think he was lying for Annie. Things got out of hand and to get back at Naomi, Annie told her that she and Liam slept together. She also said: "It's weird how every guy who loves u ends up falling in love with me," which is actually true.
"Look, I owe u a huge apology."
Finally in episode 11 of season 2 entitled And away they go the truth about Jen being the girl Liam slept...
