Frances Bean Cobain looks set to marry L.A. rocker Isaiah Silva after they reportedly got engaged.

The 19-year-old beauty - the daughter of the late Nirvana rocker Kurt Cobain and Hole singer Courtney Love - is said to have confirmed on her Facebook profile page that she accepted her boyfriend's proposal after changing her relationship status on the social networking site to 'engaged'.

She then posted: "Getting to spend the rest of my life loving my best friend makes me the luckiest woman in the world."

Frances has been dating Rambles musician Isaiah - who is said to be the spitting image of Kurt, who died in 1994 when she was just 20 months old - for just over a year and they now spend most of their time at the $1.825 million home that she bought earlier this month near LA's Runyon Canyon.

A source confirmed the news of the couple's engagement, explaining to In Touch Weekly: "Yes, she's engaged and they moved in together in a Big House near Runyon Canyon."
