Singer LeAnn Rimes showed her stripes (quite nicely!) at a birthday dinner for a songwriter pal at Nobu in Malibu Wednesday night, along with hubby Eddie Cibrian and his two young sons, Mason and Jake, and RadarOnline.com has the pics.

The family looked casually chic and seemed ready for autumn as photographers snapped away outside the trendy Japanese eatery.

After the dinner, Rimes tweeted a photo of her planting a kiss on birthday boy Darrell Brown with the cryptic caption: "Great great birthday night with the L the E the R the D the L the M the J the L And the D. moby.to/szfzl7"
