Cory Booker gushed over his girlfriend Rosario Dawson during an appearance on Ellen on Wednesday and even teased the idea that the pair may have a White House wedding if he wins the 2020 presidential election.

Booker, 49, told host Ellen DeGeneres that Dawson - who enthusiastically confirmed their relationship last week - had been 'ambushed' in the airport with questions about their romance.

'She was TMZ'd. She was visiting me in DC and she left to the airport and she got ambushed at the airport. I got a little video of her at the airport saying "I got TMZ'd. I don't have make-up on, this and this and that."

'She was wonderful, she's just an incredible human being,' he said.

He added that Dawson is a 'deeply soulful person' who has 'taught him a lot of lessons about love'.

'Sometimes you show your greatest strength when you make yourself vulnerable.

'She really has this nurturing spirit that's made me more courageous, not just in the love that I project and want to see in our country but even in our personal relationship, just to love more fearlessly. I am really, really blessed,' he said.

Ellen then joked that they should wait until after the election to get married if they intend to.

Booker did not recoil at the suggestion.

'You're saying if Rosario and I get there, wait. Don't do the marriage before? In January 2021?

'Would you help preside over the wedding? Is that a promise?' he said, then shook Ellen's hand.

Booker was also full of praise for his host.

The Democratic presidential candidate was full also full of praise for his host who he said was patriotic as a 'leader for the spirit of goodness, kindness, decency'

'Can I just thank you. I want to interrupt right now. You really are a leader for the spirit of goodness, kindness, decency.

'Patriotism is love of country but you cannot love your country without loving your fellow countrymen and woman and that love that you give, to me is patriotic,' he said.

Dawson said earlier this month she was grateful to be with Booker who is 'kind, loving and caring'

He also told of his intention to have a female running mate and vowed to bring 'grace and decency' back to politics and condemned President Trump's recent tweets about the late John McCain as 'repugnant' and 'unacceptable'.

Dawson, 39, was forthcoming when asked if she was in a relationship with Booker last week.

'Yes very much so,' she answered when asked if the pair were in a relationship, adding: 'He's a wonderful human being. It's good to spend some time together when we can.'

She went on to gush over Booker, 49, as a 'kind', 'loving' and 'caring' person but said she had 'no idea' if the pair would get married any time soon.

'I am just grateful to be with someone that I respect and love and admire so much who is so brilliant and kind and caring and loving.'

Dawson added that she believes her boyfriend's 2020 campaign will be successful.

Neither Booker nor Dawson has been married.

She has a daughter, Lola, who she adopted when the child was 11. Booker does not have any children.
