Kate Beckinsale fires back at Instagram troll who claimed she dresses 'like a teenager'

Kate Beckinsale is not taking Instagram trolling without a fight. Or at least a sarcastic retort.

The "Underworld" star, 45, continued her Instagram troll-fighting, clapping back at a comment offender who criticized her post from earlier in the week featuring her in workout apparel.

"When anxious, wear at least two pairs of trousers and several bras just to tether anything that could panic and kick out," Beckinsale captioned the photo in a self-deprecating tone.

Selma Blair was a fan, cheering the photo on in the comments with, "Be hotter."

But one troll sniped, "u dress like a teenage but ur a older lady."

Beckinsale went right there with the grammatically challenged writer. With sarcastic guns blazing, the star struck back with, "hahaha omg you’re a hoot, can we hang out."

Once would have done. But Beckinsale posted that three times.

"Dead," wrote the next user, referring to the original troll. Another wrote, "@katebeckinsale is my favorite anti-troll troll."

In February, Beckinsale was rolling over Instagram trolls who criticized her relationship with "Saturday Night Live" star Pete Davidson, who is 20 years her junior.

When one bearded Instagrammer expressed disappointment with her "dating choices" in the comment area, Beckinsale looked deep into his soul, er, profile photo, and replied, "Fairly let down by your wonky beard but thought possibly rude to say."
