The Sun can reveal the Bedroom Floor singer whisked the blonde to Rome for a romantic weekend away as they take their relationship to the next level.
Splashing the cash on serious luxury, Liam Payne booked a suite at the stunning five star Hotel De La Ville in the centre of the Italian capital.
The regal like rooms boast marble bathrooms with giant bathtubs and separate walk-in showers as well as his and hers sinks as well as built in state-of-the-art speakers.
The hotel, which is located a short walk from the Colosseum Trevi Fountain, also included a Roman Spa complete with a number of rejuvenation therapies.
A source said: “Liam and Kate are really loved up right now. It’s all very new but also very exciting for them both.
“They flew out for a romantic weekend in Rome together with Liam booking a stunning suite in the Hotel De La Ville in the centre of the capital.
A few fans spotted them but for the most part they were able to go totally under the radar which was perfect for them.
“Liam’s had somewhat of a rocky year but he seems in a much better place right now.”
Liam and Kate first went public with their blossoming romance last month after enjoying a night no the town in London as they celebrated Halloween.
The couple dressed up as Pamela Anderson and Tommy Lee before heading to posh Mayfair show restaurant Inca.
Kate- who is friends with model Chantel Jeffries – is from New Jersey and went to top university Charleston in South Carolina.
Earlier this year Liam was linked to Miami based model Aliana Mawla after they they were snapped together.
However, despite fan speculation, The Sun told in July how they were a flash in the pan coupling.
A source said at the time: “To say they were boyfriend and girlfriend is far too strong but obviously they were seeing each other.
“They both had fun but it’s fizzled out and are now very much single. There’s no bad blood.”
Liam admitted last summer while on a break from ex-fiancé Maya Henry that he struggles when it comes to dating.
He Steven Bartlett on Diary of a CEO podcast: “I feel like more than anything at this point, I’m more disappointed in myself that I keep on hurting people. That annoys me.”
