This week the stars didn't disappoint when it came to sharing photos from their childhoods and from early on in their careers.

Jennifer Lopez reminded her fans that she too went to high school and participated in sports before she became the superstar she is today.

The 46-year-old stunner took to Instagram on Sept. 10 to share an epic throwback image, which appears to have been taken during her days of track and field at Preston High School in the Bronx, reported E! Online. Lopez captioned the image with inspiring hashtags like #nevergonnagiveup and #alwayspushing.

In a birthday tribute to one of her sisters, Brazilian supermodel Gisele Bündchen gave her 6.1 million followers on Instagram a peek at what she looked like as a child.

Bündchen shared an old childhood photo of her and her sister together, and captioned the photo with, "Sweet Fofa you are an angel on earth. You make a difference in the lives of everyone you touch. Thank you for bringing so much love and compassion to the world. Happy Birthday. I love you so much!"

Nina Dobrev shared images from her childhood all week, beginning with one of her and her older brother Alexander Dobrev last Friday. On Sept. 10, the 26-year-old posted a photo of herself as a little girl holding two pet rats, reported MTV.

Dobrev joked and questioned whether it was sanitary. "Are those rats? Why am I playing with rodents? That can't be sanitary! I look pretty stoked about it though... #TBT," she captioned the adorable photo.

On Sept. 11 she joked about the juicing trend in Hollywood and shared another childhood photo of herself with a juice box.

Thalía took to Instagram to share a video of herself working out, but, in the process, also revealed that she was watching none other than her own telenovela "Marimar." The character is one of the actress and singer's most successful and beloved roles.

Television personality Lili Estefan may be known for being a host on "El Gordo y La Flaca," but the Cuban star was once a model on the popular television show "Sábado Gigante." Estefan shared a photo from 1991 of her modeling days with show's host Don Francisco on Instagram.
