Miley Cyrus' mother Tish is ''so happy'' about her daughter's engagement.

The 'LOL' actress' boyfriend Liam Hemsworth - who she met on the set of movie 'The Last Song' - proposed to her last month, and Tish Cyrus claims he is the ''love of her life''.

She wrote on twitter: ''Wow! All of the love pouring out for Miley and Liam is incredible! So happy for my precious baby girl and the love of her life!(sic)''

Despite only being 19, sources close to the young star claim she is ready to get married.

An insider told Us Weekly magazine: ''She's very mature. She's 19 going on 40 so she is ready for marriage. Liam likes her wild side, but Miley's also mature and supportive. They're both ready for this.''

Miley and Australian actor Liam have been dating since 2009 and apart from a brief split in August 2010 they have been together since.

She tweeted thanks to her fans yesterday (06.06.12) for wishing her well on her engagement.

She wrote: ''thank you for all the love today :) I'm happy to share this news with you all. I feel like all my dreams are coming true. have a great day(sic)''
