She did it! Jessica Simpson shared a gorgeous selfie on Instagram Thursday, March 6, showing off her slim figure — and jaw-dropping weight loss. The 33-year-old Weight Watchers spokesman announced that she's officially reached her weight loss goal.

Simpson posted a photo of herself looking svelte in a form-fitting Alexander McQueen dress from her new ad for Weight Watchers. "First time rocking a white dress this year . . . but not the last!!Thanks @weightwatchers!" she captioned the picture. Simpson then shared a glam selfie and added: ". . . AND a white T-shirt!! #goalreached thx @weightwatchers."

In the close-up snapshot, Simpson strikes a sexy pose in a tight white T-shirt that shows off her toned arms. With her hair up in a bun, Simpson shows off her slim face.

The fashion mogul is mom to daughter Maxwell, 21 months, and son Ace, 7 months, with fiance Eric Johnson. Feeling good about her post-baby body, Simpson also shared adorable photos of her children on Instagram Thursday.

The proud mama captioned a close-up photo of her beautiful blonde daughter pouting her big full lips. "The most beautiful girl in the world," Simpson captioned the photo.

She also shared a photo of herself giving her son a big hug while smiling for the camera. "The most handsome boy in the world," she wrote. Little Ace looks adorable in the picture, wearing blue pajamas festooned with white whales.

"This body made two amazing little human beings. I love this body and what it's capable of — no matter what size," Simpson said in an earlier Weight Watchers ad. "But this version feels really good."

Simpson is set to wear white again later this year, when she and Johnson finally plan to tie the knot. "We don't have an actual date but we do know that we want it to be this year," Simpson explained on Good Morning America on Jan. 7. "We need to get married."

Maxwell's baby brother has arrived! Jessica Simpson and fiance Eric Johnson have welcomed their second child, a baby boy named Ace Knute Johnson, her rep tells Us Weekly exclusively. Little Ace was born in Los Angeles via scheduled C-section on Sunday, June 30, the rep adds.

"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," her rep tells Us. "Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."

The singer, 32, and Johnson, 33, are already parents to daughter Maxwell, nearly 14 months. Us exclusively revealed in November 2012 that Simpson was pregnant again just seven months after Maxwell's birth; Us also broke news in February that Simpson planned on naming her child "Ace." (Ace's middle name honors dad Eric's Swedish paternal grandfather, Knute Johnson.)

In true Jessica fashion, the Fashion Star mentor accidentally confirmed the sex of her second baby-to-be to back in March. "The crazy thing is I never knew a wiener could make me nauseous," she joked of her morning sickness. After realizing her mistake, Simpson added, "Well, I guess I just told the world that I'm having a boy!"

And gender wasn't the only difference for pregnancy number two. In an interview with Ellen DeGeneres on March 7, Simpson shared that "this pregnancy is the complete opposite. Like with Maxwell, I felt amazing. Like I could do everything, eat everything. Do whatever I wanted. I had a lot of energy," she recalled. "This time around . . . I'm like exhausted. Eating Tums. That's my snack of choice."

After about six months of dating, Simpson and Johnson, a Yale grad and former NFL player, got engaged in fall 2010, but were forced to postpone their nuptials twice due to her unexpected, back-to-back pregnancies. But a source recently told Us they're hoping to (finally!) tie the knot soon.

At the Weight Watchers spokeswoman's April 14 baby shower, she "was telling friends she wanted to get married a few months after the baby is born," the source told Us. "Jessica said, 'Let's have this wedding already before I get pregnant with another one!'"
