53yrs old Michelle Obama looks sensational in white bikini and cut-off shorts as she and daughter Malia enjoy a winter weekend at the beach (Details, pics)

Michelle Obama and her eldest daughter Malia made a rare appearance in swimsuits as they are enjoying the sun in Miami.

The mother and 19-year-old daughter were spotted walking off Miami Beach on Saturday surrounded by friends - including former Obama administration senior advisor Valerie Jarrett - and Secret Service personnel. Michelle, 53, looked sensational in a white bikini top matched with high-waisted white denim cut-off shorts as she trudged her way barefoot through the sand, holding her shoes in one hand.

The former first lady also sported a long white blouse, a bandanna and large fold hoop earrings for the outing. Malia was looking similarly casual alongside her mother in a tan hoodie over her swimsuit, of which just her black bikini bottoms were visible.

The tall teen toted in her hands a pair of white sneakers and her iPhone with a charger. The also was carrying a hefty-looking book - perhaps a bit of holiday break homework from Harvard University, where Malia is due to return later this month.

The ladies looked as though they didn't have a care in the world, appearing as though the post-White House life suits them just fine. On the same day, Malia and Michelle were seen leaving their hotel with a large number of bags before grabbing some dinner at the trendy Prime 112 steakhouse and heading out of town.

The day at the beach appeared to be all about girl time as former president Barack Obama was nowhere to be seen. Malia looked stunning in a black and white patterned romper, looking all smiles outside of the restaurant, with her mom appearing in similar great spirits right behind her.

Michelle strutted out of the celeb-friendly eatery looking typically fashionable in a set of flowing high-waisted trousers with a neutral green tank and long blue cardigan. While it's not clear where youngest Obama daughter Sasha may be, she was hitting the Miami Beach at this time last year, gaining plenty of attention as she donned a swimsuit and enjoyed the sun with Joe Biden's daughter and another female friend.

She accessorized the look with a number of chains as well as a black purse with a lengthy strap.

Malia is currently enjoying a well-earned break from her studies at Harvard after the whole Obama family got together in Hawaii over the Christmas period. According to the University's website, students are due back on January 22 for Spring term.
