Jessica Simpson couldn't help but gush over 'baseball stud' son Ace after he won the championships for his team.

The 40-year-old singer penned a lengthy tribute to her seven-year-old, where she talked about his 'athlete mentality,' and detailed his game-winning home run.

Sharing a black and white photo of him on the pitcher's mound, she remarked among other things: 'This kid is good at EVERYTHING.'

'My baseball stud won the championships with a hitting a home run against an undefeated team at the end of the ballgame.'

Adding: 'He told me that he saved that hit for that moment so the team was caught off guard. Now that is athlete mentality if I do say so myself...and he is only 7.

'This kid is good at EVERYTHING and excels under pressure. He says he doesn't feel pressure though because he knows what he can and will get done out there on the field.'

'He is so happy they won the championships but now is on the all star team and will only get better. This house and his family are SO proud of him!!!'

She continued to add that her mom Tina Simpson was also present and that she 'might have busted [her] eardrum' from screaming so loud.

In early May she revealed that she had an intuition when she was pregnant with Ace that he would 'dominate a baseball field.'

'I told everyone and anyone who'd listen that he would dominate a baseball field when he was old enough and would more than likely never ever end up putting the bat down...so far my intuition was correct,' she shared, adding: 'when mama knows she knows...'.

The With You singer shares Ace, and daughters Maxwell, nine, and Birdie Mae, two, with husband Eric Johnson who was a former NFL player.

The pair celebrated 11 years together on May 21 after she met him in Italy around her 30th birthday and they swiftly got engaged less than a year later.

Simpson released a tell-all memoir called Open Book where she spoke about her struggles with weight after rising to fame as a teenager, which included years of diet pills.

Her weight has yo-yoed throughout her various pregnancies, but recently she lost 100 pounds after giving birth to Birdie.

Through healthy diet and exercise she was able to shed the weight, but isn't focusing on a number on the scale or her size. 'I just want to feel good and be able to zip my pants up,' she said in an April TODAY appearance.

And granted what she has gone through, a source said that she wants to be a good 'role model' for her children and doesn't want her daughters to 'experience what she's suffered mentally.'

'She wants to set a great example for her children and be a role model to them,' an insider told Us Weekly. 'With them getting older, they're going to go through body changes soon, so she just wants to make sure she can properly educate them on what being healthy really means.'
