Only hours after checking herself into rehab on Jan. 17, Lindsay Lohan was on the phone, chatting with OK!. I’m doing so great, thanks, the 20-year-old singer and actress told OK! in an exclusive interview from her suite at L.A.’s Wonderland Center rehabilitation facility. I’m fine. Nothing to worry about. Thank you so much for checking in, I do appreciate it. Before this conversation, Lindsay had released a statement through her rep to explain her actions, saying, I have made a proactive decision to take care of my personal health. But, when OK! caught up with her, she appeared to be in good spirits. I’m actually watching American Idol at the moment and laughing so hard!
