Jackson Rathbone, who plays pathokinetic "Twilight Saga" vampire Jasper Hale, is a father.
Rathbone and girlfriend Sheila Hafsadi, 24, had their first child together Thursday.
"Thank you ALL for the love & support! Sheila & I couldn't be happier to have such a beautiful, healthy baby boy, Monroe Jackson Rathbone VI," the 27-year-old actor tweeted.

And think again if you're feeling the name is yet another in a string of Hollywood's odd monikers. Rathbone's full name is Monroe Jackson Rathbone V, hence the baby's VI. The proud father toasted the occasion by posting photos of his father, IV if you're keeping track, and himself smoking celebratory cigars.
"Taking a cue from MJR IV... What a glorious day! Love and respect, Bone Daddy," he wrote.
Hey, Jackson, ever hear of second-hand smoke?
The baby boy was born at 9:43 a.m. on Thursday and weighed in at 8 pounds, 11 ounces, his rep told People.
The rep announced the pregnancy in February. Hafsadi, a burlesque dancer, met Rathbone while he was touring with his band 100 Monkeys. He has since left the band because of personal and career demands, according to MTV.
But Monroe Jackson Rathbone VI isn't the only baby making headlines on the"Twilight"plane. Rathbone's costar, Cam Gidandet, who played villainous vampire James in the original "Twilight" film, announced Thursday that he was expecting his second child with girlfriend Dominique Geisendorff.
Rathbone will return with costars Kristen Stewart, Robert Pattinson and Taylor Lautner in "The Twilight Saga: Breaking Dawn -- Part 2," the final installment of the films based on Stephenie Meyer's novels, on Nov. 16.
Dirty diapers and feeding schedules might have to wait, however. Rathbone and Co. are set to continue promoting the film at Comic-Con International in San Diego next week.
