Christina Applegate is married ... with big bling!

The former "Up All Night" star got hitched over the weekend to baby daddy Martyn LeNoble and now we're getting the first look at her giant wedding ring.

The sparkler she's now sporting is actually a modified version of her engagement ring. Both the original and redesigned versions were done by famed jeweler Neil Lane.

"We took her engagement ring and fit it in a sleeve of little diamonds to become one with the wedding band," Lane says. "It's platinum and diamond inset with tiny little diamonds everywhere."

"It was just the right time," the jeweler says of the couple's nuptials. "They're a very happy couple. There is a great deal of love between them."

The is the second marriage for both Applegate, 41, and LeNoble, 43, who have been together since 2008. The pair got engaged on Valentine's Day 2010 and welcomed daughter Sadie Grace in January of 2011.
