Gabrielle Union dresses up as Gwen Stefani for ‘90s birthday party and Lil Kim shows up!

Oh, she’s just a girl!

Gabrielle Union was that Hollaback Girl this weekend! The 46-year-old actress enjoyed a “Sweet Escape," throwing an early Halloween birthday bash for herself with friends and family. 

At the ‘90s-themed soiree, Union went full ska rock, dressing as No Doubt front woman Gwen Stefani. She shared a video of herself running down the stairs in a blonde wig, white crop top that reads “Gwen” and plaid pants with chains on them. 

Union got fully into character, jamming out to Stefani’s “Just a Girl.” The real Stefani was obsessed with the costume, reposting the video to her own page and writing, “@gabunion obviously this made me sooooo happy!! Gx.”

But that wasn’t Union’s only birthday surprise. At the bash, there was a special guest attendee — Lil Kim! The 44-year-old rapper broke it down on the dance floor with Union, jumping into the party while her track, “The Jump Off,” was playing and rapping along. She then went on to perform “Crush on You,” much to the crowd’s delight. 

And it wouldn’t be a Union party without some precious couple moments between Union and her hubby, Dwyane Wade. 

The pair sang and danced to Mary J. Blige’s “I’m Goin Down” in a sweet video that Wade, 36, shared to his Instagram account. 

“Last night was AMAZING!!!” he wrote.

Happy Halloween! 🎃 . Tomatillo Salsa 1 almost full gallon size bag of tomatillos (from my garden🤗). 3 cloves of garlic, trimmed but not peeled 2 whole jalapeños (or more if you want more spice) 2 or 3 limes Salt Olive oil 1 or 2 ripe avocados . 1. Preheat oven to 325F and line a baking sheet with tin foil. 2. Remove husks from tomatillos. Rinse and dry. Place on baking sheet. 3. Drizzle and coat with olive oil. 4. Add whole jalapeños and garlic to baking sheet. 5. Bake for about 30 minutes. You want the tomatillos softened, but not bursting. Jalapeños and garlic should be soft, as well. 6. Pull stems off jalapeños. Squeeze garlic from its shell. 7. Transfer everything to blender. Squeeze in lime juice and add a little salt. 8. Blend until smooth (leave the lid off a bit and cover with a towel to let the steam escape). 9. Transfer to bowl and let cool. 10. Refrigerate. 11. Add more salt to taste. Add diced avocado. 12. Cast a spell. Yum.
