The Kardashians are known for their style, and it looks like Kourtney's son might have started taking fashion advice from his new stepdad.

Just weeks after she wed Blink-182 rocker Travis Barker, reality TV star Kourtney has taken to Instagram to show off her seven-year-old's new punk rock trim.

In the black and white snaps shared to Kourtney's Instagram page, her youngest son, Reign, can be seen modeling what can only be described as a striking new look - a spiky, gelled mohawk. His 42-year-old mom captioned the post with a razor emoji and a rock-and-roll hand sign.

Many fans were quick to speculate that the new look was a mark of Travis' influence on Kourtney's kids. She shares Reign and his two older siblings - Penelope, nine, and Mason, 12 - with her ex-boyfriend Scott Disick.

The dramatic mohawk was a signature look of Travis' back in 2004, and one that he gave his own son Landon in 2009 when they walked the red carpet for Transformers: Revenge of the Fallen.

"Travis is rly effecting this family [sic]," one fan commented, while another added, "Ok Travis influencing that whole house," and a third agreed Reign looked like "a mini Travis in the making lol...that little Mohawk."

Reign's new look also got the endorsement of several certified rockers, including Avril Lavigne - who commented several heart emojis - and Skye Hoppus, the wife of Travis' Blink-182 bandmate Mark Hoppus, who gave him three rock-and-roll hand emojis.

Meanwhile, the seven-year-old is not the first of Kourtney's kids to experiment with whacky hairstyles since she and Travis became an item. Her daughter - nine-year-old Penelope - has also been spotted sporting her own punk style in the form of reddish-purple hair.

Kourtney and Travis made headlines last month when they tied the knot for the third time in a lavish Italian wedding ceremony. The entire Kardashian klan jetted out to Portofino to celebrate the nuptials, which took place a week after the newlyweds were legally married in Santa Barbara, California, and a month after they enjoyed a practice ceremony in Las Vegas.
