Brandi Glanville flashes her derriere as she imitates iconic 1976 Athena Tennis Girl poster

It's very difficult to play tennis with only one racket.

But single mother Brandi Glanville was more preoccupied imitating the iconic Athena Tennis Girl poster than actually having a proper match on a Los Angeles court Friday.

The 40-year-old reality star flashed her derrière in a skimpy tennis outfit just like cheeky 18-year-old model Fiona Walker did back in 1976.

Angeles court Friday

The original: Fiona Walker, seen here in 2011, was just 18 when she posed for the iconic 1976 pin-up poster

But thankfully the Real Housewives of Beverly Hills star opted to wear tiny white trunks under her white mini-skirt.

Brandi topped her athletic skort with a white sports bra and matching trainers.

Glanville finished off her bouncy girlish look by fastening her blonde extensions into two low pigtails.

PDA: The leggy mother-of-two's tennis partner was six-year-old Jake, who took turns playing with Brandi's red-tinged racket

The doting mother-of-two's tennis partner was six-year-old Jake, who took turns playing with Brandi's red-tinged racket.

Brandi was extremely affectionate with the black shorts-clad youngster, whom she lavished with kisses in between serves.

Not seen Friday was Glanville's other son with ex-husband Eddie Cibrian - 10-year-old Mason.

One racket, two players: Brandi tossed a ball towards Jake who held the racket like a baseball bat

He can't hit it back! It must be very difficult to play tennis with only one racket
