Kylie Jenner and Travis Scott went on a road trip to Texas this week.

The 'Keeping Up With the Kardashians' star - who is rumoured to be pregnant with her first child - has tried to keep a relatively low profile in recent weeks but couldn't escape eagle-eyed fans when she and her boyfriend traveled to his hometown.

En route to his home in Houston, the pair stopped off at MOD Pizza, where the 20-year-old reality TV star ordered a pepperoni-topped cheesy delight, before she headed back to the car and waited for her beau to bring out the food.

A source told UsMagazine.com: ''Kylie checked out the stuff and then said she wanted a pepperoni pizza and headed back to the car. Travis stayed inside for a little and joked around with the staff that was working there. Someone asked him if he was Travis Scott and he jokingly said no, and then finally admitted it was him.''

The 25-year-old rapper then returned to the pizzeria a few minutes later because Kylie had seemingly left her phone behind on the counter but, despite their delay getting back on the road, the pair seemed to be in ''good spirits.''

Although the couple - who have been dating since April - are yet to confirm their baby news, it's believed the brunette beauty has hired an entire team of people to help make carrying her unborn tot as easy as possible.

A source said: ''Kylie hired a pregnancy coach too, who will help her with nutrition and exercise, as well as take her through Lamaze training when she gets further along. Kylie is definitely not taking any chances when it comes to her unborn baby!''

The 'Life of Kylie' star is also said to have beefed up her security in the run up to her labour, as well as hiring four new assistants to help with the running of her business.
