Kim Kardashian's boyfriend Pete Davidson will reportedly miss out on her sister Kourtney Kardashian's rumored Italian wedding to Travis Barker.

A source told Us Weekly on Friday, that the 28-year-old is unable to make it because he's set to appear on this weekend's episode of Saturday Night Live, which will be his final episode on the sketch show.

Kim and the rest of the Kardashian-Jenner clan touched down in Portofino, Italy on Friday, with the family stepping out for a pre-wedding dinner in the city with Kourtney and Travis. 

Kourtney and Travis' rumored Italian nuptials are reportedly set to take place at Portofino's Castello Brown sometime this weekend.

The couple, who got engaged in October after less than a year of dating but over a decade of friendship, officially tied the knot last Sunday during a courthouse wedding in Santa Barbara.

Prior to that, Kourtney and Travis stunned fans in April by getting hitched at a wedding chapel in Las Vegas - though the drunken nuptials were not legally binding.

Pete's alleged absence from the couple's Italian 'I dos' may come as quite a surprise to Kardashian fans as the comedian and Kim have been practically glued at the hip.

The couple began dating in November of last year after sharing a kiss in a sketch during Kim's Saturday Night Live hosting gig in October.

Since then, Kim has made the relationship Instagram official and recently made her red carpet debut with Pete at The White House Correspondents' Dinner in late April.

The duo also climbed the steps of New York City's Metropolitan Museum of Art during their appearance at the star-studded Met Gala earlier this month.

Despite immersing himself in the high-profile Kardashian lifestyle, Pete has continued to relish in his comedy roots, with a Netflix special on the way.

But it was announced on Friday that Pete would be bidding farewell to SNL following Saturday's 47th season finale.

Davidson first appeared on Saturday Night Live in 2014 and quickly became one of its breakout stars.

He has since been featured in a total of eight seasons of the groundbreaking program.

It was reported that the comedian would be finishing up his run during Saturday's episode, which will be hosted by Natasha Lyonne and feature Japanese Breakfast as a musical guest.

According to The Hollywood Reporter, Kate McKinnon, Aidy Bryant and Kyle Mooney are also expected to announce their departures during the episode.

Davidson hinted at his coming departure from the series during an interview with The Hollywood Reporter, where he noted that he did not expect to stay with the program for as long as he did.  

'Yeah, I'm good. I'm surprised I made it to seven. I'm ready to hang up the jersey,' he stated.

The performer went on to express that he had matured greatly from his earlier years on the program.
