Charlie Sheen has just become engaged for a fourth time!

The 48 year-old announced on Saturday that he will tie the knot with adult movie star Brett Rossi, according to TMZ.

Sheen, who has five children and one grandchild, made this year's Valentine's Day a big one as he flew Ms Rossi on a private jet to Hawaii and popped the question on Saturday morning (Feb 15th).

The 'Anger Management' actor's publicist Jeff Ballard confirmed the news to People on Sunday (Feb 16th) and released a statement on Sheen's behalf which read;

"With all due respect to Donna -that maiden Klay-Vinn was annulled," referring to his first marriage to Donna Peele, which ended in annulment.

"Therefore, if 'three' truly is a charm; The mashup/acronym of the real CS, (Charlie & Scottie) HAS to be; 'Char-M-stee...'" he added.

Sheen's future wife posted a photo on her twitter account of the pair posing for a snap on the island with the sea in the background on the day of the proposal, and on Friday she shared a pic of a rose and a box of chocolates with the caption, "The start to an epic day!"

On Feb 14th she also tweeted, "Happy Valentine's day to the love of my life & my best friend! Everyday is Vday when I'm with you @charliesheen."

No reference to a proposal or marriage was made by Rossi.

Sheen and his second wife, Denise Richards, walked down the aisle in 2002 and have two daughters together, Sam J. Sheen (9) and Lola Rose Sheen (8). Richards filed for divorce nearly three year into their marriage, and while she was six months pregnant with Lola.

The former 'Two and a Half Men' star also tied the knot with Brooke Mueller in 2008, but after a turbulent relationship they divorced in 2011. The pair share twins, Bob and Max (4), with each other.

Congratulations to the happy couple!
