Liam Hemsworth popped the question! Miley Cyrus announced to People Magazine that she is engaged to be married to Liam Hemsworth. In a statement the 19-year old singer and Hannah Montana actress says, "I'm so happy to be engaged and look forward to a life of happiness with Liam."

Liam, 22, proposed on May 31st with a 3.5 carat diamond ring from jeweler Neil Lane. The celebrity jeweler told People that Liam asked for "something unusual. Something really beautiful and romantic." Liam and Neil Lane went back and forth until Liam was satisfied. The final pick was a 3.5 carat cushion-cut diamond handcrafted in 18-karat gold. The ring has a distinct art nouveau pattern with handcarved diamond floral motifs. The center stone is highlighted by smaller stones set in the gold band. The jeweler says, "The light flashes and sparkles no matter where Miley moves her hand." The center stone is an antique from the late 19th century. Neil Lane says, "It was hand-cut around 1880 or 1890 and it's unique and in its original form. At that time no two diamonds were alike, as they were all hand-cut, so it's fascinating to look at because it hasn't been re-cut to look contemporary over the years. I find that really romantic."

Lee DeWyze, winner of the 2010 edition of American Idol, proposed to his girlfriend Jonna Walsh. Lee, 25, proposed to his model girlfriend, 26, on a private yacht on July 16th. A glass of champagne in one hand and Disney World fireworks in the background provided the right atmosphere for the proposal. Lee tells People Magazine, "Jonna is a Disney freak. They were playing love songs on the boat and I got down on my knee and asked her. I had a speech prepared but it all went out the window, so I just asked her. She started crying and I said, 'Is that a yes?'" A "yes" it was. The couple are planning a fall 2012 wedding.

Lee and Jonna met last October at the casting for his music video of Sweet Serendipity. Lee says, "We were casting and I saw her and said, 'Let's go with her.' I though she was cute." Jonna proved to be more than just cute, when the two had a great time at their first date. "We hung out and we went to a Lakers game on our first date. She's a Lakers fan and I'm a Chicago Bulls fan and we just clicked out of the gate." Is it a problem that Jonna roots for another team? "We're seeing a counselor about that," Lee jokes.

The couple has only dated for 8 months, but they are certain of each other. Lee says on the topic, "When you know, you know. We both feel that way. We don't need to be together for 20 years before we figure it out." The only thing Lee needed help with figurin out? The engagement ring, he asked Jonna's sister for help, before he picked an engagment ring.

The lovebirds are enjoying their time as a newly engaged couple, "We do all kinds of stuff together. We go to plays and exhibits and Jonna is really into the planning of the wedding."
