Though she's nine months pregnant, Adriana Lima has another family issue weighing on her shoulders; her Maltese dog Ivy has been missing for days.

The Victoria's Secret supermodel has tried various media outlets along with social media to help spread the word that her adopted pooch, who she welcomed into her life eight years ago, has gone missing.

Celebrating all of the ladies that give so much of themselves to provide the best lives that they possibly can for their children, Hollywood's stars join all those around the world in expressing the extreme gratitude to all of the moms out there on this Mother's Day holiday.

Keeping things short and sweet, Justin Bieber took to Twitter this morning while posting a heartfelt message reading, "HAPPY MOTHER'S DAY!"

While Adriana Lima is currently months into her second pregnancy, she showed off her still spectacular washboard stomach for the new Victoria's Secret campaign.

Baring her skin in several stringy and sexy bikinis, the 30-year-old looks incredibly fit in the new shots and video compiled as part of the 2012 SWIM campaign.
