After performing her new song "Swingin'" on The Tonight Show, LeAnn Rimes grabbed a bite at Malibu hot spot Nobu.

The sexy 29-year-old country songstress showed off her long and lean gams ... paired with a plunging black shirt and satin fitted jacket. Stunning!

And guess who LeAnn grabbed a drink with Wednesday night? Giuliana Rancic! The two had a minor feud earlier this year when Giuliana made comments about LeAnn's weight, but they've totally made up! LeAnn Tweeted, @GiulianaRancic My amazing to talk to you over drinks. I adore you! You are beautiful and we were meant to meet for a reason ;)

Immediately after dinner, LeAnn got the call that hubby Eddie Cibrian injured his Achilles tendon ... even needing stitches. Rimes Tweeted:

    "My husband is hurt...stitches in his Achilles! going home.....nurse Le on the red eye :)
