Karina Smirnoff is showing off her brand new 4.5 carat Asscher Cut diamond engagement ring as she announced her engagement to St. Louis Cardinals pitcher Brad Penny.

The couple has been dating since 2009 when Karina ended her engagement to Dancing With the Stars co-star Maksim Chmerkovskiy. They were introduced by mutual friend and UFC superstar Chuck Liddell.

Smirnoff told People Magazine that the couple wanted to keep their engagement quiet for a while because they wanted time to celebrate with their families before the new became public knowledge.

She said, "We kept it quiet because my family is in New York and Brad's family is in Oklahoma so we kind of wanted them to come out and celebrate and be a family first before we let the cat out of the bag..."

Karina was seen wearing her engagement ring at Tao Las Vegas's five-year anniversary party, and even though Penny was not in attendance, he sent her a fortune cookie containing a handwritten note...

Oh yeah, and an Everlon diamond necklace.
