Christina Applegate definitely has something worth flashing -- a diamond engagement ring!

The "Samantha Who?" TV star briefly showed off her engagement ring while dodging the paparazzi at the Los Angeles International Airport on yesterday.

Applegate, 38, got engaged to Porno for Pyros bass player, Martyn Lenoble, 41, on Valentine's Day after dating for two years.

According to The Diamond Information Center, the vintage Edwardian ring features approximately 4 carats of diamonds and has an estimated price tag of $70,000.

The actress's fiance must be paying close attention to diamond trends, as the romantic rock is right in line with leading ladies like Meryl Streep who are wearing simpler bands.
