Alessandra Ambrosio gives a hint about her waistline by wearing unbuttoned pants and a tank top to lunch with her look-alike, Anja, in Beverly Hills

Alessandra Ambrosio experienced some mother-daughter time when she went out to lunch with one of her best friends.

The longtime supermodel was spotted heading to Il Pastaio in Beverly Hills with her daughter Anja and her boyfriend, who appears to be YouTuber Matheus Mazzafera.

The former catwalk queen led the group to the restaurant, where the trio were set to enjoy some of the fine Italian dishes served by acclaimed chef Giacomino Drago.

The Brazilian-born beauty seemed a little flirtatious as she wore a pair of navy trousers, the top of which was unbuttoned and folded down to reveal blue denim on the inside.

Ambrosio struts her way with plenty of confidence and charisma, showing off her amazingly taut waist as she just paired the pants with a cropped white tank top.

To complement her casual-cool ensemble, the Gal Floripa co-founder also wore a pair of white leather trainers and a white sweater for when the temperature should drop.

To top off her overall look, the mother-of-two wore her dark brown locks long, straight and flowing down her shoulders to about mid-back with a center parting.

Anja, 14, seems to be becoming more and more like her famous mother as she approaches her teens.

Not quite as tall as mom yet, the high schooler wore cream low-rise pants, a black crop top and black sneakers.

She also let her lightened locks fall long, albeit with an added dose of volume and a center parting.

Anja was also prepared for a possible cold by taking a light-colored sweatshirt with her into the restaurant.

Her pal went for a casual-cool look in white pants with a hole in the knee, a fitted washed-out black t-shirt and white sneakers.

Like his girlfriend, he wore dark sunglasses on the way from their parked vehicle to the restaurant, as the sun was just setting and the temperature had risen to over 30 degrees Celsius.

Here's how it works: The longtime supermodel was obviously feeling a little flirtatious, leaving the top of her navy blue pants undone to reveal her amazingly defined waist, to match her cropped white tank top and white trainers

ALE… Who likes a messy, textured updo? She wrote in the caption before speaking out for her hair: “@dimitrishair #dimitrishair #alessandraambrosio.”

Alongside Anja, Ambrosio is also the proud mother of her ten-year-old son Noah, whom she shares with ex-fiancé Jamie Mazur.

The former couple first got engaged in 2008 and stayed together for more than ten years until they decided to call off the wedding and go their separate ways in 2018.
