Rihanna’s often wayward behaviour has been criticized in the past as not being appropriate for someone who is a role model to young girls.

However, it appears that her own mother is not concerned by the singer’s bad attitude.

Monica Braithwaite didn’t bat an eyelid as she sat and watched her daughter make a one fingered gesture as she posed for a photograph.

The two women were out shoe shopping together as part of Monica’s birthday celebrations when Rihanna decided to flash her bad girl side.

The Rude Boy singer stuck her tongue out and swore at the camera as her mother sat next to her in the footwear store.

Rather than make Rihanna refrain from the unladylike behaviour Monica sat with her legs crossed while also posing in a pair of sunglasses.

The pop star captioned the picture: ‘Me and Mama Fenty doing some bday damage! She’s radical man! #phuckyobirthday’. (sic)

With her mischevious behaviour out of her system the singer later began acting more childlike and lay across Monica’s lap.

Rihanna posted another image with the caption: ‘Getting comfy! I always feel so safe and at home laying just like this on her lap!’

Special day: Rihanna and her mother Monica messed around in the shoe store together

It is thought that the mother and daughter were out shopping together in Beverly Hills, California on the famous Rodeo Drive.

The Umbrella singer had earlier visited Yves Saint Laurent and Valentino before heading to the more accessible stores of Bebe and Tiffany’s.

She emerged from the jewelry retailer with one of their famous blue bags after picking out something small.

Matchy, matchy: Rihanna wore a chambray shirt with rolled up sleeves that perfectly matched her high-waisted pencil skirt

For her shopping day, the Rude Boy singer wore a chambray shirt with rolled up sleeves that perfectly matched her high-waisted pencil skirt.

Her very late Nineties-style skirt was extremely distressed, ripped all the way along its hem and it also had a number of holes in both the front and the back.

One of the rips exposed the star’s shapely bottom and gave those walking behind her a glimpse of her thong, but in true RiRi-style she strode with her head held up high happy to look controversial.
