Rosie Huntington-Whiteley isn't the only member of her family to have been blessed with super-sexy genetics. Check out her hunky brother, Toby Huntington-Whiteley!

The 24-year-old personal trainer and model is making his TV debut in a sizzling new commercial for Jacamo clothing.

In the ad, the sexy stud models shoes, a tight T-shirt and more for the fashion brand. Toby shares a laugh with fellow male models while flaunting his bulging biceps and pecs on the fitted tee. In addition to his rock-hard body, we can barely take our eyes off Toby's full lips and signature pout! Hot damn.

Toby took to Instagram this week to promote his new Jacamo commercial with a sexy photo. "A shot from my TV ad debut with @jacamouk. Thank you! #models1 #m1men," he wrote.

Toby previously showed off his six-pack abs and ripped muscles in a shirtless campaign for Jacamo in which he modeled swimwear. It's no secret why Toby, who is repped by Models 1, was chosen for the steamy shirtless photo spread.

Martin Roberts, head of buying for Jacamo, previously said, "Jacamo is about offering men of all shapes and sizes a choice of fashion that fits, regardless of size. Standing at a broad 6 feet, 4 inches tall, Toby was the perfect fit to launch our SS15 product." We agree!
