She's been embroiled in a public feud with her husband Eddie Cibrian's ex-wife Brandi Glanville.
And LeAnn Rimes' hands-on maternal approach with Brandi's son Jake is sure to rile up her nemesis further.
The 30-year-old singer was seen placing a protective hand on her six-year-old stepson's back after his baseball game on Saturday in Los Angeles with Eddie, 39, while Brandi, 40, stood alone on the sidelines.
LeAnn appeared relaxed but in
charge as she walked with her hand on the six-year-old boy's back as
they walked to their car after the game.
She cut a far healthier figure that in recent months as she showed off her curves in a black T-shirt emblazoned with the words 'Pow! Bam! Happiness' across the front, paired with baggy jeans folded at the ankle.
The singer kept it casual with silver flip flops and a matching silver shoulder bag that sported a gold chain as a strap.
LeAnn wore her dark blonde hair in loose waves over her shoulders, and shielded her eyes with brown aviator shades.
She wore minimal makeup save for a slick of rosy pink lipstick and some peachy blusher.
The star stayed hydrated with a bottle of mineral water, and carried a large reusable Whole Foods shopping bag.

Jake looked adorable in his white sports uniform and blue baseball cap as he sipped on a giant chocolate milkshake.
LeAnn's husband Eddie, meanwhile, looked handsome in a white V-neck T-shirt and brown trousers paired with Nike trainers.
The actor wore a backpack and carried two large black foam pads as he walked alongside his son.

But Brandi kept her distance, cutting a
lonely figure as she arrived alone and stood by herself on the
sidelines.
The reality star looked extremely thin in blue skinny jeans and a black and white sweater, which she paired with high-heeled brown leather platforms.
She wore her blonde hair in loose waves over her shoulders and shielded her eyes with aviator sunglasses.
LeAnn is reportedly shopping around a comedy series based on her real life and hopes to star in the show alongside her husband.
A source told UsMagazine.com: '(They) have been shopping around a scripted comedy based on their lives together. They would play versions of themselves, kind of like on "Curb Your Enthusiasm."'
The insider also revealed that the couple plan to include a 'crazy ex-wife' in the show that will be inspired by Brandi, who has had numerous public spats with LeAnn.
But LeAnn and Eddie have decided not to feature his sons with Brandi, Mason, nine, and Jake on the show.
The source said: 'Mason and Jake are not involved. If kids end up being on it, they would be played by actors -- not Eddie's children.'
Another friend close to the couple said: 'They've met with a few networks. Nothing is finalised yet, but they're seeing where the show could go.'
