Jada Pinkett Smith has celebrated her 42nd birthday by opening up about her past addictions on her Facebook.com page.

The actress has revealed she struggled with addiction in the past, but has conquered her problems thanks to her "wisdom", "heart" and "conscience".

She writes, "What I learned about myself is this, when I was younger I was not a good problem solver, meaning I had a very difficult time with dealing with my problems in life. I had many addictions, of several kinds, to deal with my life issues, but today, at 42, I have my wisdom, my heart and my conscience as the only tools to overcome life's inevitable obstacles."

Pinkett-Smith, who turned 42 earlier this month (18Sep13), did not detail the nature of her addictions, but insisted they're part of the past.

She adds, "I have become a good problem solver with those tools, and I am damn proud. Thank you for all the love that was given to me for my birthday this year. What I hope is that we all continue to gain healthy understanding that life is really about, solving problems, and also about us learning to become masters at solving them."

Her latest post comes just days after Pinkett-Smith offered fans a revealing Facebook message about her stance on divorce after a friend had asked for her marriage advice.

She wrote, "For the past five years, I have been meeting with elders who have been married for 25+ years to get understanding from many perspectives as to what marriage and love is all about. Almost all the couples have said that at some point in their marriage they have stumbled upon inevitably difficult moments that called for a break."

The post follows on from ongoing rumours about the status of her own marriage to Will Smith - for years the couple has battled split and divorce stories.

In her note to her friend, Pinkett-Smith added, "My hope for you is this, that you consider taking the route that some of our elders have taken in giving your marriage some space and time before the drastic decision of divorce. Answers to big questions need time to find lasting truth vs the truth of the moment. After this process the answer may be the same, but at least you will have the clarity to go about it all with certainty and integrity, but you may also find that spark that could save and rekindle your marriage."
