AN embarrassed mum has apologised after claiming her little boy mistakenly wore an X-rated t-shirt to school.

Shelly McCullar, from Texas, US, posted pictures of her son Anthony on Facebook wearing the mortifying top.
The t-shirt in question features a pair of woman’s legs which intentionally resemble McDonald’s golden arches along with the fast food giant’s catchphrase “I’m Lovin’ It.”

In the social media post, Shelly insists that the raunchy shirt was in a basket of hand-me-down clothes given to her by a friend.

Shelly says while Anthony wore the top for an entire day, no one at his school appeared to notice the saucy innuendo.

She said: “Once again, my sincere apologies to the teachers and staff at Travis Elementary.

Mum ‘accidentally’ sent son to school in this VERY rude T-shirt

“I promise from now on to monitor what my kids are wearing! I had no idea Anthony wore this to school!!

“Just to clarify, I would never let my kid wear something like this.

“A friend had given me some hand me down clothes for Anthony. I haven’t had the chance to completely go through them. I will tonight though!!
