Travis kept his arm around Kourtney as they walked down the path to the lobby doors, though she was more steady after getting a few strides in.
Kourtney and Travis took their opportunity in Sin City to tie the knot at the One Love Wedding Chapel according to a Tuesday morning report from TMZ.
It was a private early morning affair as sources told the publication that the famous pair did not allow the venue to take any photos and opted to bring their own photographer and security.
Insiders close to the couple initially said they came prepared with a marriage license which they presented to the chapel's owner who also served as a witness.
However, a source at the chapel later told TMZ that they did not actually get a license and therefore the marriage is not 'legal'. There is no record of the couple applying or receiving a marriage license at Clark County.

The website for the One Love Wedding Chapel also explicitly states: 'a legal marriage license must be obtained prior to the marriage ceremony.'
The couple said to be planning 'several' other wedding celebrations to follow.
Of the nuptials, One Love Wedding Chapel owner Marty Frierson told People: 'I didn't know who it was until they pulled up. I advertise as 24-hours but they wanted to make sure I was still there. They paid and they requested Elvis Presley, that was mandatory. I called back 5 minutes later and was like, I got an Elvis, and there they were.'
'They came, got married, tossed the bouquet in the driveway, and danced to Elvis,' Frierson said. 'They showed a lot of love and had a lot of fun.'

Frierson added: 'There was a lot of that - kissing and hugging. They barely came up for air! They just seemed totally in love.'
He also revealed that Kravis' wedding party consisted of four people in total, with guests documenting the happy occasion on their phones.
'They all had iPhones, taking pictures and videos from every angle,' he revealed. 'I don't know if they were the friends or their social media team. They filmed everything from the time they walked in, to the time they walked out. The vows, the kiss, the rose bouquet toss, the dancing. I usually take pictures for the chapel but they wanted to handle it all themselves.'
