Rap star Kanye West has surprised Kim Kardashian West by gifting her a neon green Mercedes-Benz SUV.

The chart-topping rapper decided to treat the reality TV star with the eye-catching 4×4 SUV, with Kim subsequently taking to her Instagram story to show off her new vehicle.

Kim - who was recently photographed getting into the same model SUV in Miami - said on her social media account: "Look who surprised me with this baby, you guys. I got the truck of my dreams 'cause I was so excited in Miami."

Kim - who has kids North, five, Saint, two, and seven-month-old Chicago with Kanye - explained that she fell in love with the car while driving the same make and model around Miami.

She shared: "Oh my gosh, I just got out of the gym and was surprised by this new baby. I loved it so much in Miami and I kept on talking about it."

Meanwhile, US President Donald Trump recently heaped praise on Kim and Kanye at a fundraising event.

The outspoken politician - who has personally met with Kanye and Kim since winning the US election in 2016 - said: "Now we're doing great and Kanye West liked me and that really lifted my ... Kanye West has some real power!

"He's got a good wife too, in Kim, I'll tell ya. She really is [great]."

Kim, 37, attended a personal meeting with the President at the White House earlier this year, when she asked for clemency for inmate Alice Marie Johnson.

Trump - who ultimately granted clemency to Johnson, who had been serving life without parole for a first-time drug offence - thinks Kim did a "great thing".

He said: "She did a great thing. She did a great thing.

"The person was in jail on a very strange thing. She was there for 22 years and it was based largely on a phone call that they were listening to and she had another 24 years."
