LeAnn Rimes Celebrates Early Eddie Cibrian and Brandi Glanville's Son's Birthday; Country Singer's Billboard Hot 100 Record Finds Competition In Mark Ronson

LeAnn Rimes celebrated the birthday of Eddie Cibrian and Brandi Glanville's son as the country singer's "How Do I Live" track's record-setting stay in the Bilbboard Hot 100 Record is in danger of being toppled by Mark Ronson.

Two days ago, LeAnn Rimes posted a birthday greeting on Instagram to Brandi Glanville 's son as she wrote, "Happy 12th Bday to my awesomely cool, handsome and silly stepson. We all love you so much!! #proudstepmom #bdaylove #happybirthdaymason."

Eddie Cibrian and Brandi Glanville's son, Mason, will turn 12 on June 8.

On May 30, LeAnn Rimes tweeted, "STEAK!! #bday dinner with the fam celebrating my #SS 12th bday!!"

One fan commented, "(You) are always always there for these two boys, thank god for you."

But others could not help but put a damper on the celebration as one of her followers noted, "At the end of the day it's not your son!! Well done Brandi and dad for the son everyone wish for!!!"

Another added, "(He) should be spending with his Mom not some stepmonster like you."

This is the kind of negativity against LeAnn Rimes and ex Eddie Cibrian that Brandi Glanville wanted to stop.

On May 21, the "Real Housewives of Beverly Hills" star tweeted, "PLEASE No more bashing of @EddieCibrian or @leannrimes on my time line- I will unfollow these people if I follow them at all.-#4mykids on&up."

In an interview with In Touch Brandi Glanville said about making nice with LeAnn Rimes and Eddie Cibrian, "It's really nice and very weird because the tide has been smooth for a little while now. It worries me that something crazy's about to happen because usually it ebbs and flows."

Meanwhile, "Uptown Funk" by Mark Ronson and Bruno Mars has matched the record set by LeAnn Rimes for the longest stay in the top 5 of Billboard Hot 100 singles chart. To date, the track has already extended its stay to 25 weeks.

"The country singer's 1997 track 'How Do I Live' is the only other single in the US chart's 55-year history to have enjoyed a stay in the Top 5 for that length of time," NME said.
