The "M.I.L.F. $" singer held her son up as they hung out with the furry character, and both looked perfectly rock-meets-country for the occasion. Fergie donned an olive green leopard print zip-up vest, black t-shirt and matching shorts, which she paired with round sunglasses and a black bandana and boots, while Axl was layered up in an orange plaid shirt, denim-and-plaid jacket, jeans and black buckle sneakers. And, seriously, can we talk about that too cute fauxhawk?
The towhead tot's add-ons were just as spot-on -- a bold blue bandana, tied around his neck just like Mom's, and a cowboy hat, which he held onto tightly.
Megan Fox and Brian Austin Green spent their afternoon kiddie-free on July 28, when they ate lunch at Killer Shrimp in Marina Del Rey, California.
An eyewitness tells ET that the pair, who are expecting their third child, smiled and held hands as they walked into the restaurant, then shared a laugh while walking to their table. A very pregnant Fox enjoyed the blackened salmon while Green chowed down on the killer shrimp dish. Both wore their sunglasses through parts of the hour-and-a-half-long meal, and at one point, "they showed each other something on their phones."
Already a mom of three, Kourtney Kardashian continued celebrating her daughter, Penelope, this month.

While Kardashian enjoyed some downtime in New England, her half-sister, Kendall Jenner, was hanging out a little further down I-95 in New York City. The 19-year-old model rocked a vintage star-patterned halter top and Levi's Redone miniskirt while visiting the MAGNUM New York store in SoHo on July 23, where she cooled down from the insane summer temps by creating her own Belgian chocolate-dipped ice cream bar.
Speaking of models, Tyra Banks just made an announcement that should make both America's Next Top Model and Dancing With the Stars fans quite happy. She and Nyle DiMarco, the winner of cycle 22 of ANTM and season 22 of DWTS (can you guess what his lucky number is?), will bring the TYRA BeautyLive + Model Search 2016 to The Venetian Resort and Casino in Las Vegas on Aug. 22. The event in Sin City will also include TYRA Beauty's first Model Search, in hopes of finding new faces for the brand's 2017 campaign.

The Neighbors 2 star wasn't the only one enjoying a movie that Saturday night. The cast of Superstore -- Ben Feldman, Colton Dunn, America Ferrera, Nichole Bloom, and Nico Santos -- laid out a picnic to enjoy while watching The Muppet Movie at Cinespia in L.A.
Sisters Maddie and Mackenzie Ziegler will be brown bagging it soon when they go back to hitting the books this fall. They got their skin back-to-school ready with Clean & Clear in L.A. -- and scored some bright backpacks!
Meanwhile, DJ Khaled chewed Stride Gum charged with Crunch Reactors while laying down a track for the brand in L.A.
Further down in Southern California, Heather Dubrow's World was taping at the Irvine Improv in Irvine, California. The podcast's namesake welcomed two of her Real Housewives of Orange County co-stars, Tamra Judge and Shannon Beador, as well as husband Terry Dubrow, as guests on her July 21 show.
Plenty of stars found themselves in San Diego last weekend, where they enjoyed all the panels and parties of Comic-Con. That included Tyler Posey and Andre 3000, who mingled with guests at the After-Con Celebrating the Women of Wonder, hosted by NYLON and NVE The Experience Agency, at OMNIA Nightclub on July 21.
Also hanging at Comic-Con was Star Trek star Zachary Quinto, who stopped by the Schick Hydro Super Shave Shop at Entertainment Weekly's Con-X Fan Festival.

The Weeknd put on his own show at the Leonardo DiCaprio Foundation's Third Annual St. Tropez Gala in the South of France on July 20. DiCaprio raised $45 million at the event in support of environmental awareness and research. His soiree was attended by a ton of A-listers, including Bradley Cooper, Bono, Mariah Carey, and Chris Rock.
Steph Curry knows his way around a celebratory dance, so it should come as no surprise that the NBA pro was a shoo-in to compete with Korbel California Champagne at the Celebrity Spray-Off at the Celebrity Golf Championship in Lake Tahoe, California, on July 21.
Equally as sports-minded, Landon Donovan -- rocking a very appropriate purple T-shirt that said "Commit" in yellow block letters -- participated in his first CrossFit Games experience with Zevia in Los Angeles on July 22.
