American’s First Son stepped out with his glamorous girlfriend Bettina Anderson for a black-tie event in Portsmouth today, as he rubbed shoulders with a beaming Nigel Farage.

Wearing a dark suit, Donald Trump Jr proudly strode into the naval city’s historic dockyard, arms linked with his Palm Beach socialite girlfriend, Bettina Anderson on Friday evening.

Ms Anderson, who was first seen locking lips with Don Jr. in September, sported a grey maxi satin dress, with a yellow jacket with accents of blue draped over her shoulders.

And beside the 47-year-old and his partner, was a beaming Nigel Farage donning a dark velvet blazer coupled with a bow tie, as the trio headed to the 250-year celebration of Britain’s oldest gunmaker – John Rigby & Co.

The exclusive event was held in the shadow of historic warships HMS Victory and HMS Warrior, where the American couple’s armoured cars were spotted.

Nigel Farage told MailOnline: ‘Don is a Rigby customer, a great British firm celebrating their 250th anniversary. I support manufacturing excellence.’ 

Avid hunter, Donald Jr, was previously invited to a showcase held by the London gun makers last month in what was described as a ‘significant milestone’ for the firm. 

During his May visit, the south London-based company spoke of their excitement about their upcoming collaboration with the influential US figure as well as the outdoor brand, Field Ethos.

At the time, Rigby managing director, Marc Newton, said: ‘Hosting Donald Trump Jr. was nothing short of a complete privilege. 

‘America represents one of the biggest markets for British gun makers so having this opportunity to spend such an intense few days with the most influential person in the US hunting industry was priceless. 

‘Rigby and Field Ethos share a passion for authenticity and our brands are aligned on so many levels. Watch this space for further announcements about how we are working together.’ 

And in a continued show of support for the gun company, Donald Jr arrived with his glowing girlfriend, to celebrate their 250th anniversary on HMS Victory and HMS Warrior today. 

Celebrations featured a cannon salute between the ships after guests enjoyed a lavish gala dinner aboard HMP Warrior, with notable speakers said to include The Earl of Yarmouth, William Seymour, 32.

As part of the anniversary, Britain’s oldest gun making firm will also release 250 limited engraved editions of their Big Game and High Stalker rifles in a celebration of the company’s history. 

This is Donald Jr’s most recent outing amid his budding romance with Anderson, who is nine years his junior.

Their relationship caused a buzz in Republican circles in Palm Beach, as the US President’s son hadn’t yet officially called off his four-year engagement to Kimberly Guilfoyle

His ex, who is also a former Fox News host, managed to stay in the Trump orbit by being nominated to be the US Ambassador to Greece.

Guilfoyle and Anderson were both present at Trump’s inauguration in January, although it was Anderson at Donald Jr’s side for certain parts of the day. 

The couple’s first document outing was in mid-December, when the the two spent nearly two hours at a hotspot in Buccan, three miles from Anderson’s West Palm Beach townhouse.

They left the high-end bistro hand-in-hand before getting into a black SUV and driving off.

Their last high-profile event, before today, saw the two attend Trump’s speech to a joint session of Congress in early March.

Trump and Anderson’s visit to Portsmouth comes shortly after the socialite made her frustration known over a recent New York Magazine article where an anonymous source called him a ‘spoiled heir.’

Anderson expressed her fury after an the insider spoke to the magazine spoke to called the president’s son an ‘a*****e.’

The insider even told the publication that Anderson’s new boyfriend ‘is the most despised member of the family.’

Nigel Farage told MailOnline: ‘Don is a Rigby customer, a great British firm celebrating their 250th anniversary. I support manufacturing excellence.’

But the 38-year-old hit back with a series of cryptic Instagram stories, first declaring: ‘Rumors are started by haters, spread by fools, and accepted by idiots.’

She then cast doubt on the validity of the source, sarcastically writing, ‘DEFINTELY an “insider” VERY familiar with @donaldtrumpjr.’

She later showered Donald Jr with praise, calling him ‘the finest, loveliest, tenderest, and most beautiful and brilliant person I have ever known’ before adding, ‘and even that is an understatement.’

Don Jr. also had his own response to the article titled: ‘The Age of Don Jr.: How the ultimate fail son became an edgelord whisperer and a bona fide power player.’

‘Don’t get me wrong, I can totally be an a*****e when I need to be…if you’re adversarial to my friends, my family, my country, MAGA, etc.,’ he wrote on Instagram.

‘But I think you’d be hard pressed to find a regular person who actually knows me that thinks that. There’s no wonder why these “sources” are always anonymous. Man up, put your name to it, but we know you wont (sic) because you’re cowards.’
