There's no longer any doubt about it: San Francisco 49ers lineman Nick Bosa is taken. Bosa, 28, and his girlfriend, model Ella Ailiff, hard launched their relationship on Sunday, November 30, posting a video via Bosa's TikTok account that showed the two getting cozy and sharing a couple kisses while sipping espresso. "Coffee and football Sunday," Bosa captioned the video. The video comes on the heels of speculation that Bosa was dating singer Megan Moroney. The rumors started when Moroney, 28, watched a 49ers game in September from a private suite in Levi's Stadium.
