The 34-year-old American forward is believed to be the second highest paid women's footballer in the world, behind Australia's Sam Kerr.
The US Women's National Team (USWNT) is the most successful team at the World Cup, having never finished outside of the top three.
But they're hoping to make history yet again this summer by becoming the first team ever to win the World Cup three times in a row.
With nine World Cup goals to her name, Morgan is the USA's fourth highest leading goalscorer at the tournament - but just six more goals at this summer's tournament would bring her to the number one spot.
That shouldn't be a problem for the star striker who easily netted six goals in six appearances when the USA won the last World Cup in 2019.

And unlike her teammate Megan Rapinoe who is set to retire later this year, the USA co-captain is showing no signs of hanging up her boots anytime soon.
"My body feels good, and I feel like I'm in the moment right now, so I'm not looking too far ahead," she said.
Morgan was part of the American side who crushed the Lionesses' World Cup dreams in 2019.
The USA knocked out England with a 2-1 victory in the semi-final, with Morgan scoring the deciding header on the day of her 30th birthday.

Her notorious 'tea drinking' celebration sparked outrage, as viewers fiercely debated whether Morgan was referencing the Boston Tea Party and American independence, mocking English tea-drinkers, or simply using the popular phrase "that's the tea", as the forward suggested herself.
Morgan's club career began when she was just 21, when she became the first overall pick in the 2011 Women's Professional Soccer Draft.
Since then, she has played for US clubs including Portland Thorns and Orlando Pride, as well as French side Lyon, where she won both the French Cup and the Champions League.
In 2020, Morgan enjoyed a brief three-month stint with Tottenham Hotspur, but injury restricted her and she scored two goals in her four appearances for the club.
Now she captains the San Diego Wave side in the National Women's Soccer League (NWSL) who currently sit 6th in the league table.
And despite missing a September 2022 international camp in which the USA were beaten by the Lionesses at Wembley stadium due to a knee injury, Morgan had an exceptional return for her club and holds the record for the most goals and the most assists for San Diego Wave this season.
Morgan's success is not just limited to the football pitch, either.
In 2013, Morgan released her first novel, Saving the Team, which debuted at number seven on The New York Times Best Seller list for Children's Middle Grade.
As a high-profile athlete with more than 10 million followers on Instagram, Morgan has been vocal about some of the issues affecting women's football, too.
Earlier this year, she criticised the idea of a Visit Saudi sponsorship at the Women's World Cup.
"I think it's bizarre that FIFA has looked to have a Visit Saudi sponsorship for the women's World Cup when I myself, Alex Morgan, would not even be supported and accepted in that country," she said.
The Saudi sponsorship plans were later dropped, amidst backlash from the co-hosts Australia and New Zealand.
Morgan was also part of the USA team who filed a discrimination lawsuit against US Soccer in 2019, which has ultimately led to them securing equal pay for their men and women's sides.
She told the BBC in June how important it was to her that the fight for equality in all spheres of the game continued.
She said: "I'm really proud of being on this national team to fight for that. Not only for ourselves, but for the future of this sport both in the US and globally."
In May 2020, Morgan and her husband Servando Carrasco - a footballer who plays for Fort Lauderdale CF - welcomed their daughter Charlie to the family.
And if Morgan was a force to be reckoned with at the 2019 World Cup, other teams better watch out because she says being a mother has only made her a better player.
Speaking to PEOPLE magazine, she said: "[Parenthood] just makes me feel more balanced all around.

"I'm able to give everything to the sport and my teams, but when I go home, I'm not dwelling on whether I had a bad training or bad game. I just have to be a mom, and tend to my child's needs instead of overanalyzing things."
Morgan will co-captain the USA when they kick off their World Cup campaign against Vietnam on Saturday.
