The 26-year-old troubled starlet - who was given $100,000 by the 'Anger Management' star to help pay off her hefty $233,904 tax bill - sent him a bunch of flowers and a hand-written letter to apologize after he revealed earlier this week that she never thanked him for his generous gift.
Sources close to the 'Liz & Dick' actress told gossip website TMZ.com that Lindsay was very embarrassed by the situation and explained in her letter to Charlie that she didn't mean to be rude but couldn't contact him because she lost his number when her phone broke recently.
The former 'Two And A Half Men' star generously helped out his 'Scary Movie 5' co-star when he heard she was having financial difficulties after not being paid for one of her projects but Charlie admitted he was unimpressed that she accepted money from him but didn't acknowledge it.
He said: "She got shorted and I found out, so I said: 'Here'. I'm still waiting for a text to say 'Thank you'. Anything you know?"
The flame-haired beauty's pals also insisted she is extremely grateful for Charlie's monetary gift but has been distracted by her ongoing legal and financial problems.
A judge revoked Lindsay's probation last week and she is reportedly facing a possible eight months in jail for lying about being behind the wheel of her Porsche during a car crash in June.
The actress sent the bouquet and letter directly to Charlie's house in a bid to repair their relationship and express her sincere gratitude.
It was recently revealed Lindsay is struggling to pay her rent and has been scraping together all the money she can in order to pay $8,000 per month for her Beverly Hills mansion in Los Angeles.
She has also fallen behind on monthly payments to a storage company, and now owes around $16,000, which could lead to items inside her locker - including designer clothes, family heirlooms and "potentially embarrassing" articles - being sold off at auction if the bill isn't paid by the end of this month.
