Kylie Jenner's boyfriend Tyga can't keep his paws off her in PDA-filled Snapchat video after Justin Bieber concert 

It was a family affair as the Kardashian-Jenners joined together to take in one of Justin Bieber's Los Angeles concerts on Wednesday.

And so of course Snapchat Queen Kylie Jenner documented the festivities - and after party - on her account, showing off her loving boyfriend Tyga, 26, in the process.

The 18-year-old could be seen flashing a coy smile as her older beau showered her with kisses in one lovey video.

Packing on the PDA: Tyga could be seen showering younger girlfriend Kylie Jenner with kisses in a video shared to her Snapchat on Wednesday evening as they partied following one of Justin Bieber's LA concerts

She showed off her newly blonde tresses, which were styled sleek and straight and fell past her shoulders.

The reality star went for a bit of an edgy look, in a low-cut black, spaghetti strap tank top, worn with a loose-fitting black windbreaker that she sported low on her shoulders.

She highlighted her features with smoky eye shadow, as well as mascara and a nude lipstick, perhaps one from her wildly popular Kylie Cosmetics lip kit collection.

She filmed a series of silly Snapchat videos along with her family as well as her romantic clip with Tyga, such as a few that played on lyrics from Kanye's hit song N***** in Paris. 

'Kim, come and meet me in the bathroom stall,' she whines in one video, filmed in a bathroom, before Kim walks onscreen.

In need of advice: In another video, Kourtney Kardashian put on an accent as she asked sister Kylie: 'My lips are actually numb. Do you think that's normal?'

The mother-of-two then quips, in a jokingly exasperated tone: 'Come on, Kylie, show me why you deserve to have it all. Come on. Show me.'

A collection of videos starred sister Kourtney, including one in which the mother-of-three put on an accent, as she could be seen holding a blue plastic cup.

While lounging on a couch in the video, the Keeping Up with the Kardashians star asked Kylie: 'My lips are actually numb. Do you think that's normal?'
