Kendall Jenner and Jacob Elordi Holding Hands in London

Kendall Jenner and Jacob Elordi are taking their relationship across the pond ... enjoying a date night in London, but stopping short of taking their relationship to the next level.

The two stars were spotted holding hands in England on Thursday night ... with Kendall looking like a lovely London fog in a form-fitting gray dress.

Jacob wore a stylish, dark blue pinstripe suit as he and Kendall walked around the city ... sunglasses on to protect themselves from the paparazzi's flashes.

While the happy couple is clearly still dating, it seems they've decided to keep work and pleasure separate for now ... because this hang came right after Jacob appeared at the premiere of his new movie "The Dog Stars" with a different cute date -- a happy, panting dog.

It looks like Jacob didn't change outfits between the premiere and his outing with Kendall.

That's right, Kendall came all the way to London, but the pair didn't make their red carpet debut ... despite an opportunity as tailor-made as Jacob's suit.

In any case, it seems their summer of love is still rolling on ... with the duo adding London to other places like Australia, Idaho and Hawaii, where they've taken trips together in recent months.
